Cross-Cultural Adaptation, Validation, and Reliability of the Persian Version of the Brief Michigan Hand Questionnaire

BACKGROUND

Brief Michigan Hand Questionnaire (Brief MHQ) is one of the most reliable and sensitive patient-reported outcome measures for hand and wrist disorders worldwide. This study aimed to assess the psychometric properties of the Persian version of the Brief Michigan Hand Questionnaire based on standard guidelines.

METHODS

One hundred two patients with various hand and wrist disorders filled the Persian version of Brief MHQ along with the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire and the visual analogue scale (VAS) for pain. Seventy-eight participants returned to complete the Persian Brief MHQ for the second time after 4 days.

RESULTS

The analysis showed excellent internal consistency with a Cronbach's alpha ranging from 0.89 to 0.91. The Persian Brief MHQ has an excellent test-retest reliability with a 0.94 intraclass correlation coefficient (ICC). The correlation coefficient of -0.74 between Brief MHQ and the QuickDASH showed a strong correlation and confirmed its validity.

CONCLUSION

The Persian version of the Brief MHQ is a reliable and valid tool to apply to Persian individuals with hand and wrist disorders.

Factors Associated with the Return to Work after Carpal Tunnel Release Surgery: A Cross-Sectional Study of the Worker Population

Background: There is controversy regarding the factors influencing the duration of sickness absence and return to work (RTW) after surgical treatment of carpal tunnel syndrome (CTS). This study aimed to determine factors related to RTW in these patients. Methods: This descriptive-analytical study was performed on all patients with CTS who underwent surgery in a main orthopaedic centre from December 2020 to April 2021. Patients were followed for 90 days after surgery for the RTW. The patients were classified into two groups based on the time of RTW, early (<21 days) and late (>21 days). These two groups were compared in terms of occupational, individual and disease-related factors and the type of surgery. Results: The mean time to RTW in patients was 23.2 ± 7.1 days, with a range of 7-60 days. There was a statistically significant relationship between early RTW and gender (female) (p = 0.005 OR = 6.5), non-manual work (p = 0.002 OR = 1.2), the total score of the Boston carpal tunnel questionnaire before surgery and job satisfaction (p = 0.04). The mean time to RTW in patients who underwent open surgery was less than in endoscopic surgery (22.89 ± 6.29 vs. 24.58 ± 4.7), but this difference was not statistically significant (p > 0.05). Conclusions: Based on the findings of our study, the type of surgery does not affect the RTW of patients with CTS. Considering the effect of job type and job satisfaction on RTW, it is recommended to pay attention to the type of occupation in addition to the type of surgery so that this workforce can RTW with good performance. Level of Evidence: Level IV (Therapeutic).

Comparing the Radiologic and Functional Outcome of Radial Shortening Versus Capitate Shortening in Management of Kienböck's Disease

BACKGROUND

Kienböck's disease is the avascular necrosis of the lunate bone. There is no consensus on the treatment strategy to avoid joint deterioration. This trial is conducted to compare the functional and radiological outcomes of radial shortening and capitate shortening techniques, in patients with avascular necrosis of lunate.

METHODS

Patients with a confirmed diagnosis of Kienböck's disease who met the inclusion criteria were randomly divided into radial shortening and capitate shortening groups and treated by allocated technique. Physical examination and radiologic evaluations were performed before and 6 and 12 months after the operation.

RESULTS

A total of 52 patients (52 wrists) of stage II or III Kienböck's disease were assessed for eligibility, 12 patients in the radial shortening group, and 17 patients remained until the end of the study. Patients in both groups achieved a satisfactory outcome, with no report of postoperative complications. None of the outcome measures, ranges of motion, grip, and pinch strengths were significantly different between the groups. The outcome was not considerably different in patients with positive or negative ulnar variances who were treated by capitate shortening technique.

CONCLUSIONS

The capitate shortening technique which is performed through a smaller incision, and takes less time as compared with radial shortening can be advantageous for patients with stage II or III Kienböck's disease regardless of the ulnar variance. This method can be as effective as classical methods such as radial shortening in improving clinical and functional symptoms after surgery while causing fewer complications.

Developed Bone Biomaterials Incorporated with MicroRNAs to Promote Bone Regeneration: A Systematic Review, Bioinformatics, and Meta-analysis Study

This systematic review and meta-analysis focused on the effectiveness of biomaterials integrated with specific microRNAs (miRNAs) for bone fracture repair treatment. We conducted a comprehensive search of the PubMed, Web of Science, and Scopus databases, identifying 42 relevant papers up to March 2022. Hydrogel-based scaffolds were the most commonly used, incorporating miRNAs like miR-26a, miR-21, and miR-222, with miR-26a being the most prevalent. The meta-analysis revealed significant benefits of incorporating miRNAs into scaffolds for bone repair, particularly in hydrogel scaffolds. However, some controversies were observed among studies, presenting challenges in selecting appropriate miRNAs for this purpose. The study concludes that incorporating specific miRNAs into bone biomaterials enhances bone regeneration, but further trials comparing different biomaterials and miRNAs are necessary to validate their potential applications for bone tissue regeneration.

Closed Reduction and Percutaneous Pinning for Treatment of Proximal Interphalangeal Joint Pilon Fractures

BACKGROUND

Proximal interphalangeal (PIP) joint pilon fractures are among the challenging hand injuries, which are often associated with a wide range of complications. This study aimed to report the clinical and radiological outcomes of closed reduction and percutaneous Kirschner wire (KW) insertion with or without bone cement application (for the fabrication of an external fixator) in the treatment of PIP joint pilon fractures.

METHODS

Twenty pilon fractures underwent closed reduction and percutaneous KW fixation through a modified technique. At the end of the follow-up period, 3 questionnaires-Quick Disabilities of the Arm, Shoulder, and Hand (Quick DASH), Visual Analogue Scale for pain, and Patient-Rated Wrist Evaluation-were completed. The radiological outcome was assessed by radiography. Range of motion, and grip and pinch strength were measured.

RESULTS

The mean follow-up period was 14.57 ± 4.03 months (range, 12-20 months). The mean range of motion of PIP at the end of the follow-up period was 89.64° ± 10.82° (range, 65°-100°). The mean difference in the range of motion in the contralateral side was 21.4° ± 13°. The mean of the Quick DASH score was 13.50 ± 2.92 (range, 11-21). Two patients had residual articular malalignment, and 3 patients had angular or rotational malunion.

CONCLUSION

By treating pilon fractures with the proposed technique, we achieved a satisfactory outcome. The acceptable articular and axial alignment was achieved in 75% of patients, and complications were low. The flexibility of percutaneous KW insertion and handmade external fixators makes these approaches convenient for treating PIP joint pilon fractures.

Four decades of hand microsurgery in Iran: A bibliographic analysis

BACKGROUND

The aim of this study was to perform a bibliometric analysis to assess the number of articles published by Iranian researchers in the field of hand and microsurgery over the last four decades.

MATERIALS AND METHODS

An online search was conducted using 685 keywords in the abstract/title sections of articles, including carpal tunnel syndrome, wrist fractures, nerve injury and repair, skin flap and graft in the hand, congenital disorders in the hand and forearm, tumor in the hand and wrist, and infection in the hand and wrist. From February 1976 to May 2021, EndNote software version 8.1 was used to search articles in PubMed and Scopus databases. Articles in which at least one of the authors was affiliated with Iran were chosen. The name of the original institution, field of study, total number of publications, type of study, collaboration rate of Iranian hand surgeons for each year, and annual sharing of Iranian articles in journals with the highest cite scores in the field of hand and microsurgery were all examined in the present study.

RESULTS

The total number of publications in the field of hand and microsurgery was 632 (an average of 11 papers per year). Most of the Iranian hand and microsurgery papers were from the capital city, Tehran (38.09%). There was an increasing trend in the number of publications over the years, most which were about carpal tunnel syndrome (21.5%), tendon (9.8%), and nerve (9.6%). In total, 59.6% were descriptive articles, whereas the proportion of clinical trials was relatively small (22.3%).

CONCLUSIONS

Iranian hand microsurgeons have continued to increase their scientific output in hand microsurgery and related fields over the last 40 years. The quality of Iranian hand microsurgeons' scientific output, both within and outside their discipline, has greatly improved; however, they still have a long way to go before becoming a hub of science.

Comparing the Severity of Injury and Trauma Pattern between Scooter and Street Motorcycle Riders; a Prospective Cohort Study

Introduction:

The popularity of motorcycle riding in Iran is increasing. However, there is a lack of information about the safety of different motorcycle types. This study aimed to compare the severity of injury and trauma pattern between scooter (vespa) and street (standard) motorcycle riders.

Method:

In a prospective cohort study, a comparison of demographics, injury severity, trauma pattern, and clinical characteristics between 324 riders (162 Vespa and 162 standard motorcycles) admitted to emergency departments was undertaken. The risk factors associated with severe injuries in the two groups were also determined. An emergency medicine specialist determined the severity of trauma based on the abbreviated injury scale (AIS).

Results:

The Odds Ratio (OR) of severe injuries was significantly higher in the standard motorcycle riders’ group (OR: 3.09; 95% CI: 1.9-4.21; p: 0.013). The frequency of lower extremity fractures was significantly lower in the Vespa group (OR: 4.11; 95% CI: 2.01-6.25; p = 0.012). The frequency of admission to the intensive care unit was significantly higher in the standard motorbike riders’ group (OR: 1.64; 95% CI: 1.11-2.51; p = 0.033). The multivariate analysis indicated that motorcycle type, the speed at the time of the accident, use of helmet, and age of riders are the most important predictors of trauma severity in riders (p<0.05).

Conclusion:

The pattern of injury varies between standard and Vespa motorcycles. The standard motorcycle riders were prone to a higher risk of adverse outcomes such as severe injuries. Due to the particular structure of scooters, the rate of lower limb injuries was significantly lower than standard motorcycles.

COVID-19 among patients with orthopedic surgery: our experience from the Middle East

Background

We report our experiences with COVID-19 in one of the largest referral orthopedic centers in the Middle East and aimed to describe the epidemiology and clinical characteristics of these patients.

Methods

During February 20 and April 20, 2020, patients who underwent orthopedic surgery and healthcare staff who were in contact with these patients were screened for COVID-19. To identify patients who were in the incubation period of COVID-19 during their hospital stay, all patients were tested again for COVID-19 4 weeks after discharge.

Results

Overall, 1244 patients underwent orthopedic surgery (1123 emergency and 121 elective) during the study period. Overall, 17 patients were diagnosed with COVID-19 during hospital admission and seven after discharge. Among the total 24 patients with COVID-19, 15 were (62.5%) males with a mean (SD) age of 47.0±1.6 years old. Emergency surgeries were performed in 20 (83.3%) patients, and elective surgery was done in the remaining 4 patients which included one case of posterior spinal fusion, spondylolisthesis, acromioclavicular joint dislocation, and one case of leg necrosis. A considerable number of infections occurred in patients with intertrochanteric fractures (n=7, 29.2%), followed by pelvic fractures (n=2, 8.3%), humerus fractures (n=2, 8.3%), and tibial plateau fractures (n=2, 8.3%). Fever (n=11, 45.8%) and cough (n=10, 37.5%) were the most common symptoms among patients. Laboratory examinations showed leukopenia in 2 patients (8.3%) and lymphopenia in 4 (16.7%) patients. One patient with a history of cancer died 2 weeks after discharge due to myocardial infarction.

Among hospital staff, 26 individuals contracted COVID-19 during the study period, which included 13 (50%) males. Physicians were the most commonly infected group (n = 11), followed by operation room technicians (n = 5), nurses (n = 4), and paramedics (n = 4).

Conclusions

Patients who undergo surgical treatment for orthopedic problems, particularly lower limb fractures with limited ambulation, are at a higher risk of acquiring COVID-19 infections, although they may not be at higher risks for death compared to the general population. Orthopedic surgeons in particular and other hospital staff who are in close contact with these patients must be adequately trained and given appropriate personal protective equipment during the COVID-19 outbreak.

Ligament Reconstruction of Traumatic Pure Dislocation of Carpometacarpal Joint of the Thumb: A Series of Acute and Chronic Cases

Background  Traumatic instability of carpometacarpal (CMC) joint of the thumb without a fracture (pure dislocation of CMC joint) is an uncommon injury, and a universally accepted protocol has not yet been developed for its management. Here, we aim to evaluate the outcome of this injury managed with ligament reconstruction technique, in a series of acute and chronic injuries. Patients and Methods  Total nine patients (six acute and three chronic) with pure dislocation of CMC joint who underwent ligament reconstruction surgery were included in this retrospective study. Outcome measures included disabilities of the arm, shoulder, and hand (quick-DASH) questionnaire; visual analog scale (VAS) scoring system; patient-rated wrist/hand evaluation (PRWHE) system; pinch and grip strength; and Kapandji thumb opposition scores. Results  The patients' mean age was 32.55 ± 11.4 years. Their mean follow-up period was 27 ± 12.8 months. The mean postoperative pinch and grip strength was equivalent to 91.5% and 108% of the contralateral hand, respectively. The mean Quick-DASH score was 14.7 ± 19.4. The mean PRWHE score was 18.7 ± 22.4. The mean VAS was 1.1 ± 1.5. The mean Kapandji score was 8.3 ± 1.4. The pinch and grip strength were considerably superior in acute injuries. Degenerative changes were seen in all joints at the latest follow-up. None of our patients needed a revision surgery. Conclusion  Ligament reconstruction method could result in favorable outcome in the management of pure dislocation of CMC joint. However, delayed surgery of this injury might adversely affect the outcome measures.

Tele-orthopaedics: A systematic mapping study

INTRODUCTION

The use of telemedicine in orthopaedics can provide high-quality orthopaedic services to patients in remote areas. Tele-orthopaedics is widely acknowledged for decreasing travel, time and cost, increasing accessibility and quality of care. In the absence of a comprehensive review on tele-orthopaedics applications and services, here, we systematically identify and classify the tele-orthopaedic applications and services and provide an overview of the trends in the field.

METHODS

In this study, a systematic mapping was conducted to answer six research questions, we searched the databases Scopus, PubMed, IEEE Digital Library and Web of Science up to 2019. Consequently, 77 papers were screened and selected on the basis of specific inclusion and exclusion criteria.

RESULTS

We found that mobile-based teleconsultation was mostly asynchronous, while non-mobile teleconsultation was synchronous. The results showed that the physician-patient relationship was more common than other interactions, such as physician-physician and physician-robot interactions. In addition, more than half of the services provided by tele-orthopaedics have been used for orthopaedic diseases/traumas in which joint replacement and fracture reduction have been the most important orthopaedic procedures. It has been noted that more attention has been paid to tele-orthopaedics in developed countries such as the USA, Australia, Canada and Finland.

DISCUSSION

Telemonitoring (teleconsultation and telemetry) and telesurgery (telerobotics and telementoring) were found to be the two major forms of tele-orthopaedics. Mobile phones were used asynchronously in most of the teleconsultations. The development of different applications may result in the use of multiple smartphones applications in real-time teleconsultation. The use of smartphones is expected to increase in the near future.

Evaluation of the clinical and radiological outcome of hemi-hamate arthroplasty in the reconstruction of proximal interphalangeal Joint fracture-dislocations

Background: Hemi-hamate arthroplasty, a new attractive method for treatment of unstable Proximal Interphalangeal (PIP) joint fracture-dislocations, offers several advantages over the previous methods. This study was designed to evaluate the clinical and radiological outcome of this procedure. Methods: In this study, 14 patients and 15 fingers with PIP joint fracture-dislocations were evaluated, including 8 acute and 7 chronic injuries. The mean age and follow-up of the patients were 35.3 years and 29.7 months, respectively. The mean PIP joint involvement was 56.6%. Objective assessment of the outcome was performed by joint alignment, motion, stability, and grip and pinch strength. Subjective evaluation of the outcome was performed using the Visual Analogue Scale (VAS) and Disabilities of the Arm, Shoulder, and Hand (DASH) score. Statistical analysis was performed using SPSS for Windows (version 16). Independent sample t test or Mann-Whitney U test were used for statistical comparison of the mean values. A p value of < 0.05 was considered significant. Results: At the final follow-up, 14 out of 15 PIP joints were clinically stable. Grip and pinch strength of the injured hand averaged 87.6% and 88% of contralateral hand, respectively. The mean PIP joint flexion, arch of motion, and flexion contracture were 82.6, 63.6, and 19 degrees, respectively. The mean DASH score was 20.33±21.87 in acute and 7.25±11.71 in the chronic group (p=0.181). The mean VAS was 2.87±2.29 in acute versus 0.42±0.78 in chronic patients (p=0.022). The degenerative joint disease was observed in 5 cases. Conclusion: Although hemi-hamate arthroplasty is a promising method for the reconstruction of severe PIP joint fracturedislocations, it is associated with minimal functional limitation and high rate of osteoarthritis.

Comparison of Radial Head Resection With Radial Head Fixation in the Terrible Triad Injury of the Elbow

Background: The optimal treatment of radial head component in the terrible triad injuries of the elbow is challenging. In this study, we compared the functional outcome and complication rates of radial head resection with radial head fixation in a terrible triad setting. Objectives: Comparison of radial head resection with radial head fixation in terrible triad. Methods: In the present retrospective study, the outcome of terrible triad injury in 41 patients, in whom the radial head component was managed with either radial head resection (n=28) or open reduction and internal fixation (n=13), was compared. The subjective assessments of the outcome included visual analog scale (VAS) for pain, ‎the Mayo elbow performance score (MEPS), and the disabilities of the arm, shoulder, and ‎hand (DASH) score. The objective assessment of outcome included the evaluation of elbow range of motion (ROM) and elbow stability. Results: The mean±SD age of the patients was 39.2±10.2 years. The demographic characteristics of the patients of the two study groups were not statistically different. The mean supination/pronation arc of motion was not significantly different between the two ‏study groups (P=0.11). The mean flexion/extension arc of motion was significantly more in the fixation group (P=0.001). The mean MEPS and DASH scores were not ‏significantly different between the study groups (P=0.22 and P=0.49, respectively). The mean ‏VAS was significantly more in the fixation group (P=0.04). All the elbows were stable at the last follow-up. The postoperative complications (arthrosis and heterotopic ossification) were considerably more in the resection group. Conclusion: Although comparable at function, the present study favors the radial head fixation whenever possible to avoid the postoperative complications of radial head reaction.

The Role of Lunate Morphology in the Severity of Kienböck Disease: A Retrospective Study

Background: Lunate morphology has been associated with several wrist pathologies. In this study, we aimed to find how lunate morphology (absence or presence of hamate facet) affects the severity of Kienböck disease. Objectives: Evaluation of the relationship between lunate morphology and kienbocks disease. Methods: A total of 106 patients with stage IIIA or IIIB of Kienböck disease at initial presentation were included in this study. Modified Litchman classification system and standardized lateral radiographs were used for staging the Kienböck disease. Lunate morphology was investigated on plain radiograph and computed tomography scan or magnetic resonance imaging and was classified into type I (absence of hamate facet) and type II (presence of hamate facet). Results: The mean±SD age of the patients was 33.5±9.2 years. Kienböck disease stage IIIA and IIIB were identified in 68 (64.2%) and 38 (35.8%), respectively. Hamate facet was present in 65 (61.3%) patients and absent 41 (38.7%) patients. A significant association was found between lunate morphology and stage of disease so that the number of patients with lunate type I was significantly more in stage IIIB and number of patients with lunate type II was significantly more in stage IIIA (p<0.001). Conclusion: Lunate morphology is associated with the severity of Kienböck disease in patients initially presented with stage IIIA or IIIB. These associations could be implicated to prevent disease progression as well as to optimize the outcome of treatment.

Intravascular Glomus Tumor of the Wrist Causing Chronic Wrist Pain

Glomus tumors are glomus body neoplasms that most commonly occur in the subungual areas of the hand, typically characterized by small nodules associated with localized tenderness, cold sensitivity, and excruciating paroxysmal pain. Extradigital glomus tumors can present a diagnostic challenge because they are rare and usually accompanied by nonspecific symptoms. Intravenous origin of the glomus tumor, especially in the wrist, is much rarer. The authors here report an intravenous glomus tumor of the wrist presented with atypical features such as insensitivity to cold and a history of long-term pain, which led to the misdiagnosis of the lesion as extensor tendonitis. Following the excision of the tumor mass, the patient's pain completely disappeared and no further pain was reported afterward. As a result, the authors suggest a more careful workup for the correct diagnosis of glomus tumors with such atypical manifestations. They also suggest considering intravenous glomus tumor in the differential diagnosis of a chronic wrist pain.

Treatment of dorsal fracture-dislocations of the proximal interphalangeal joint using the shotgun approach

This study assessed the outcome of open reduction and internal fixation of proximal interphalangeal joint fracture-dislocations through a shotgun approach, while keeping hemi-hamate arthroplasty as a back-up plan. After using the shotgun approach, fixation was carried out when the anterior fragment was large enough to accept two 1.5 mm screws. Sixty-three fracture-dislocations were treated in 61 patients, of whom 30 underwent internal fixation. Twenty-one of these were assessed in the final study. At a mean follow-up of 29 months, the mean range of joint motion was 80° and 102° for the injured and contralateral hand, respectively. The mean pinch and grip strengths of injured hand were 82% and 83% of contralateral hand, respectively. The mean disabilities of the arm, shoulder and hand score was 5.5. The mean visual analogue pain score was 1.6. Surgery through the versatile shotgun approach allows excellent intra-operative assessment and acceptable outcomes.

Evaluation of functional outcome after nonsurgical management of terrible triad injuries of the elbow

BACKGROUND

Terrible triad (TT) is one of the severe injuries of the elbow that generally requires surgery. Nonsurgical treatment has recently been applied in selected cases of TT injury. Evaluation of the results of this treatment was the main aim of this study.

METHODS

In a prospective cohort study, 10 patients with a mean follow-up of 30.6 months were evaluated. The inclusion criteria included a congruent joint after closed reduction, no indication for surgery of the coronoid and radial head fractures, no block in supination and pronation up to 60°, no intra-articular fragments, and a free and stable joint with ulnohumeral extension up to a minimum of 45°. Mayo Elbow Performance Index and Disabilities of the Arm, Shoulder, and Hand score were used for assessment of the functional outcome. A standard physical examination to record elbow range of motion was also performed.

RESULTS

For the affected and the contralateral elbows, respectively, the mean extension of the elbow was 11° ± 7° and 0.0° ± 2°; the mean flexion was 131° ± 9° and 140° ± 10°; the mean supination was 58° ± 17° and 85 ± 7°; and the mean pronation was 53° ± 23° and 85° ± 7°. The mean Disabilities of the Arm, Shoulder, and Hand score was 4.76 ± 5.17. The mean Mayo Elbow Performance Index was 95 ± 8.16.

CONCLUSION

Nonsurgical management of the TT injury can result in acceptable functional outcomes when a patient meets the criteria set for nonsurgical treatment.

Osteochondritis Dissecans of the Humeral Head: A Case Report and Review of the Literature

Osteochondritis dissecans (OCD) is a common joint disorder in knee, ankle and elbow, however it can be rarely found in glenohumeral joint. In this study, we report an asymptomatic case of humeral head OCD, which was detected incidentally following a trauma. X-rays showed an area of lucency around an oval bony fragment measuring about 1 cm on the superior aspect of the humeral head. However, the patient was pain-free and the shoulder range of motion was normal.

Distal Radius Radiographic Indices and Perilunate Fracture Dislocation

BACKGROUND

Distal radius radiographic indices may play a role as risk factors in pathogenesis of Kienbock's disease, scaphoid fracture and nonunion. Perilunate fracture dislocations are devastating wrist injuries, and their relationship and distal radius indices have not been addressed in the literature.

OBJECTIVES

The aim of this study was to evaluate the possible role of distal radius radiographic indices including radial height, radial inclination, ulnar variance and volar tilt as risk factors in the perilunate fracture dislocation injury of the wrist.

PATIENTS AND METHODS

We studied distal radius radiographic indices including radial height, radial inclination, ulnar variance and volar tilt in 43 patients with perilunate fracture dislocations and compared them with 44 wrists in the control group.

RESULTS

The mean values of the radial height, radial inclination, ulnar variance and volar tilt were 12.74 (5 - 18), 24.20 (7 - 35), -0.73 (-5 - 4) and 12.28 (2 - 20) in the patient group. These values were 12.68 (9 - 22), 23.22 (17 - 30), -0.11 (-4 - 3) and 11.05 (-3 - 20), respectively in the control group. There was no statistically significant difference between the two groups.

CONCLUSIONS

This study did not show that distal radius anatomical indices including the radial height, radial inclination, ulnar variance and volar tilt influence perilunate fracture dislocation as risk factors.

Avulsions of Triceps Brachii : associated injuries and surgical treatment ; a case series

This study reports the clinical presentations, intra -operative findings, type of the treatments, outcome of the treatment and specially associated injuries in patients with the avulsion of the distal end of the triceps brachii (TB) tendon. We studied 6 patients with rupture or avulsion of the distal end of the TB tendon. The medical records, imaging files, clinical outcomes at the final follow up visit were reviewed. The clinical outcomes were assessed by Mayo Elbow Score at the final follow-up visit. All patients were male, 4 of them having injury in the left hand as the non-dominant hand. Mean age of them was 34.5 years. All cases had small bony fleck in the posterior of elbow in lateral radiograph. Three patients had associated injuries -including intra-articular fractures and medial collateral ligament rupture. In one case V-Y plasty of the distal TB was done. In 4 patients the results of surgery were excellent, one was good and one was fair. Although TB tendon rupture is rare, it should be -considered in differential diagnosis of the upper -extremity trauma and its associated injuries should be addressed properly.

Chondromyxoid Fibroma of Pelvis, Surgical Management of 8 Cases

BACKGROUND

Chondromyxoid fibroma is a rare benign primary bone tumor of cartilaginous origin, which most commonly involves the metaphyseal bone of proximal tibia and distal femur. The purpose of the study is to report our experience with diagnosis and surgical management of Chondromyxoid fibroma in the pelvic region.

METHODS

Eight consecutive patients with a final diagnosis of pelvic Chondromyxoid fibroma were treated from 2001 to 2010. We considered the presentations and outcome for surgical complications and local recurrence after extended curettage and allogenic corticocancellous bone grafting.

RESULTS

Three patients were female and five were male. The median follow up period was 72 (30-126) months. The mean age of cases was 31.9 (20-41) years. Five patients had left side involvement and in the remaining three, the right side was involved. Four involved periacetabulum, two involved the ilium and the remaining two cases were ischiopubic. The mean Musculoskeletal Tumor Society Score was 94.1%. The major complications were recurrence in one case and herniation after pubic rami resection in another case.

CONCLUSION

Chondromyxoid fibroma should be distinguished from chondrosarcoma. Management recommendation includes extensive curettage and corticocancellous bone grafting. We also advocate use of fibular strut allograft for reconstruction of pubic rami after its resection to prevent hernia in cases with pubic rami involvement.

A proximal femur aneurysmal bone cyst resulting in amputation: a rare case report

Aneurysmal bone cyst (ABC) is blood filled expansile cystic lesion that most commonly occurs in patients during the second decade of their lives. Traditionally it has been described as a benign lesion but can be locally aggressive and result in the destruction of the involved bone. Treatment methods include surgical excision and curettage with or without bone grafting. We report a proximal femur aneurysmal bone cyst, which resulted in the amputation of the lower extremity, even though all available classic methods of treatment were applied for it.

Lunate intraosseous ganglion cysts and chronic wrist pain- reporting six cases

BACKGROUND

Intraosseous ganglion (IOG) cysts rarely have been reported in the carpal bones and lunate is the most common area of involvement. They can present as chronic wrist pain accompanied by a radiolucent lytic lesion in the lunate bone. We provided a retrospective review of six cases of intraosseous ganglion cysts within the lunate bones that all of the patients presented with chronic wrist pain.

METHODS

We retrospectively reviewed the medical records, pathologic reports and imaging files of the six patients who were referred and treated due to chronic wrist pain with final diagnosis of the lunate intraosseous ganglion. All cases were treated by curettage and autologous cancellous bone grafting. 

RESULTS

There were six patients with final diagnosis of the lunate IOG who received surgical treatment. Four out of six patients were female and the remaining was male. Mean age of the patients was 33 years (22 - 56). Right wrist was involved in four patients. Pain was the chief complain in all patients. Mean time of suffering from the wrist pain till referring to hand clinic for definite treatment was nine months (3 - 24). Mean duration of follow up was 30.6 months (6 - 48). The wrists became pain free after surgical treatment and no graft absorption or recurrences were seen in the control radiographs obtained throughout the follow-up period.

CONCLUSION

Diagnosis of intraosseous ganglion was based on the imaging features and clinical presentation. Although most cases of the lunate bone IOGs are symptom free and found incidentally after wrist imaging performed for other reasons, these lytic lesions should be included in differential diagnosis list of chronic wrist pain especially in the presence of increased uptake in bone scan located on the lunate area.

An unusual case of radial polydactyly, (tetraplication of the thumb, duplication of the radial carpal bones and bifurcation of the radius)

Radial polydactyly, the most common digital duplication in Asian and white populations, has a wide range of manifestations. Its classification is useful for planning and assessing surgical treatment. Our patient had four thumbs, duplicated radial carpal bones, and a bifurcated radius. This presentation is not covered by any of the current classifications. To the best of our knowledge, this is the first case of such characteristics reported to date. Consequently, we propose some modifications in the nomenclature and classification of radial polydactyly.

Aneurysmal bone cyst of the capitate: a rare case report

Primary aneurysmal bone cyst (ABC) in the hands is rare. It occurs more commonly in metacarpal bones and involvement of carpal bones is very uncommon. We report the third case of ABC in the capitate, its clinical presentation, imaging findings and treatment.

Clinical and radiological results of fixation of acromioclavicular joint dislocation by hook plates retained for more than five months

Background:

Hook plates are used to treat acromioclavicular joint dislocations. Our study took into consideration the patients’ outcome following treatment with clavicular hook plates retained for more than five months.

Objectives:

Our aim was to assess the response to treatment of acromioclavicular joint dislocation by clavicular hook plate when retained for more than five months.

Patients and Methods:

We treated 24 patients who had acromioclavicular joint dislocation with a clavicular hook plate between 2008 and 2012 at our hospital. We did not repair the coracoclavicular ligament. In all patients, the plate remained more than five months because they did not come back at the recommended time for removal of their plates. The follow-up period ranged from five to thirty three months with a mean of nineteen months.

Results:

The main complication was osteolysis that was seen in two patients. The mean constant score was 94.5 ± 8.77 out of 100 with a range between 70 and 100.

Conclusions:

Our study showed that the use of clavicular hook plates was a good treatment option for acromioclavicular joint dislocation. However, scores were lower in case of prolonged presence of plates.

Habitual dislocation of the hip: a rare case report

Habitual dislocation of the hip (HDH) in children is a rare entity and can be a causative factor for popping or snapping hip which is a common problem in children with good prognosis. We report a case of HDH in a 9 year old girl who was suffering from frequent snapping hip at night, its course and treatment process.

Ulnar variance in scaphoid nonunion

BACKGROUND

Negative ulnar variance can be a risk factor in Kienböck's disease, wrist instability, and scaphoid bone fracture. This study focused on the ulnar variance in wrists with scaphoid bone nonunion.

METHODS

We retrospectively reviewed posteroanterior wrist radiographs of 65 patients who were diagnosed as established scaphoid nonunion and underwent open reduction and bone grafting between 2005 and 2010. We used reference radiographs from contralateral wrists of 65 consecutive skeletally- mature patients with distal radius fracture as the control group and then measured ulnar variance and compared it in both groups. 

RESULTS

Ulnar variance was measured in standard posteroanterior wrist X-rays of 65 scaphoid nonunion and 65 normal controls. Twenty five patients (38.5%) in the scaphoid nonunion group had negative ulnar variance, and the mean value was -0.26 (± 1.24) mm (range: -3, +2). In the control group, 15 subjects (23.1 %) had an ulnar minus wrist, and the mean ulnar variance was + 0.54 (± 1.47) mm (range: -3, +4) .The difference in ulnar variance was significant between the two groups (P-value = 0.001).

CONCLUSION

Ulnar variance may influence developing of nonunion process in scaphoid bone fracture.

An unusual case of preaxial polydactyly of the hand (triplication of the thumbs)

Preaxial polydactyly is the most common duplication pattern in white and Asian populations (1). It is a congenital anomaly with a wide range of manifestations. Current classification do not have the capacity to classify all different types of radial polydactyly. We describe here a very rare and unusual case of bilateral preaxial polydactyly (triplication) in a woman and report the operations results. We have not found similar case in the literature. Our case is unique and did not fit into the classification systems described for thumb polydactyly.

Osteoid osteoma of the hand and wrist: a report of 25 cases

BACKGROUND

The hand and wrist bones are infrequent sites for osteoid osteoma, and its diagnosis can be difficult. This paper reports 25 cases of osteoid osteoma in the hand and wrist.

METHODS

Records of the 25 patients who had pathological conditions of osteoid osteoma of the hand and wrist were reviewed and analyzed.

RESULTS

Twenty-five cases of osteoid osteoma of the hand and wrist were treated in 20 years period. The average age was 25.2±7.6 years (range, 16 to 46 years) with men to women and right to left side ratio of 5.25 and 4 respectively. The most common site was in the proximal phalanx (ten cases). The diagnosis was made using x-rays, three- phase Technetium bone scans, CT, and MRI and all the diagnoses were confirmed by histological examination. The average time from the onset of symptom to successful treatment was 16.3±11.1 months, and at a mean follow-up of 36.6±46.9 mouths. Five recurrences of disease took place in which three of them were operated elsewhere. All five patients subsequently were treated and cured by reoperation.

CONCLUSION

Osteoid osteoma is relatively rare lesions in the hand and wrist that can be a persistent source of hand and wrist pain. Patients under age of 40 who have otherwise unexplained pain should be evaluated.

Chondromyxoid fibroma of calcaneus

BACKGROUND

Chondromyxoid fibroma is a rare benign primary bone tumor composed of immature myxoid mesenchymal and cartilaginous tissue. Its occurrence in calcaneus is very rare and few cases of calcaneal involvement have been reported in literature. We report five cases of CMF in calcaneus.

METHODS

Five cases, with the final diagnosis of chondromyxoid fibroma of the calcaneal bone are included in this report. Preoperative tumor workup was performed for our patients. We reviewed and recorded demographic data and the sign and symptoms of patients at presentation to our center. Mode of treatments, postoperative complications and recurrence were also studied. Curettage, high speed burring and bone grafting was performed in 4 of our patients and in the remaining case we only carried out curettage and burring.

RESULTS

Of the five patients, 3 were male and 2 were female. The mean age at presentation was 21. Two of our cases had previous surgery in other centers and had been referred to our clinic because of recurrence. The chief complaint in all of our patients was heel pain. The mean follow up period was 25.2 months. All of our patients had a delay in the diagnosis of tumor. We did not have any recurrence in our patients during follow up period.

CONCLUSIONS

This case series shows that chondromyxoid fibroma is not necessarily as exceedingly rare as generally reported in the current literature. This tumor should be considered in the differential diagnosis in patients with ankle and heel pain.

Reconstruction of distal fibula with osteoarticular allograft after tumor resection

BACKGROUND

Involvement of distal fibula by benign aggressive and malignant tumors usually necessitates resection of the involved segment of fibula. Numerous techniques have been proposed to reconstruct the ankle joint after this procedure, which can result in complications. We introduce reconstruction of ankle joint by fibular osteoarticular allograft.

METHODS

Reconstruction of the distal fibula after wide resection of tumor was carried out in four patients. There were two cases of Ewing sarcoma, one case of osteosarcoma and one giant cell tumor. After wide resection of tumor, we reconstructed the lateral side of the ankle joint by osteoarticular fibular allograft, which was applied and internally fixed with semitubular plate and screws. In the follow up period, we did assessment of complications, pain and ankle joint instability.

RESULTS

The mean age of our patients was 24.2 years (12-31). The mean follow-up was 3.2 years (1.5-6.7). In follow up visits there were no signs of infection or wound healing problems. Union was achieved in all patients.

CONCLUSION

In cases of benign aggressive and malignant tumors involving the distal fibula, we can recommend resection of the distal fibula and reconstruction of the ankle with osteoarticular allograft of the distal fibula.

Radial inclination and palmar tilt as risk factors for Kienböck's disease

Radial inclination angle (RIA) and palmar tilt (PT) of distal articular surface of radius, are anatomical factors that influence force transmission across the wrist and load transfer to the lunate. The purpose of this study is to evaluate the relationship between these parameters and Kienböck's disease. We measured and compared RIA and PT in standard posteroanterior and lateral wrist x-rays of 55 patients with Kienböck's disease and 60 controls. The mean RIA was 25.5° in Kienböck's disease patients and 23.3° in the control group (P = .002). The mean PT was 11.5° and 9.4° for patients and controls, respectively (P = .005). All of these differences were statistically significant. We concluded that there is an etiological association between higher degrees of RIA and PT with Kienböck's disease.

Axillary artery injury with proximal humerus epiphyseal separation: a rare case report

Fracture of the proximal humerus associated with vascular injury has rarely been reported in children, and only two cases have been reported in the literature. In adults this combination has been reported more frequently. We present the case of a 14 year old boy with proximal humeral epiphyseal separation and axillary artery injury.

Radiographic indices in one hundred fifty normal Iranian wrists

BACKGROUND

Radiography is the most widely available imaging modality. Precise evaluations of wrist x-ray can help diagnosis and evaluate the prognosis of many wrist disorders.

METHODS

We measured length, angles and indices in 150 posteroanterior and lateral wrist x-rays to determine normal dimensions and variations according to age and sex. All x-rays were made with standard exposure, with the wrist and forearm in a neutral position.

RESULTS

The average carpal height ratio was 0.52±0.03 with the Youm method and 1.5±0.09 with the Nattrass method. Mean ulnar variance was +0.99±1.6 mm and mean radial inclination was 25±4 degrees. The average radial tilt was 10±5.1 degrees. Mean scapholunate angle was 50±8.4 degrees (normal range 40-60).

CONCLUSION

Carpal height, third metacarpal and capitate length were smaller in women than in men. There was a significant positive relationship between all dimensions. Our data base may be used to follow-up in conditions such as carpal instability, osteoarthritis and osteonecrosis, as well as for clinical research.

Bilateral combined Monteggia and Galeazzi fractures: a case report

We present an exceedingly rare case of left Monteggia-Galeazzi fracture-dislocation and right Monteggia-distal radius fracture occurring simultaneously in a 20-year old male patient who had fallen 13 meters from a building. The combination of Monteggia and Galeazzi fracture-dislocation in the same forearm is very rare and, to the best of our knowledge, simultaneous bilateral Monteggia and Galeazzi or distal radius fracture in the same patient, have never been reported.

Osteoblastoma of the scaphoid bone - A rare case report
