Index pollicization: an evolution of ideas and techniques from a paediatric orthopaedic institution

Pollicization has been a very successful procedure in the treatment of specific types of hypoplastic thumb. Although much has remained the same since early descriptions of the procedure in the 1800s and 1900s, refinements over the years have made it safer and more predictable. Over the years at our institution we have studied, modified and refined our incisions to produce a new thumb that is aesthetically pleasing with excellent function. We present our technique for pollicization along with pearls and pitfalls we have discovered.

Does expanded polytetrafluoroethylene mesh really shrink after laparoscopic ventral hernia repair?

BACKGROUND

The shrinkage of mesh has been cited as a possible explanation for hernia recurrence. Expanded polytetrafluoroethylene (ePTFE) is unique in that it can be visualized on computed tomography (CT). Some animal studies have shown a greater than 40% rate of contraction of ePTFE; however, very few human studies have been performed.

STUDY DESIGN

A total of 815 laparoscopic incisional/ventral hernia (LIVH) repairs were performed by a single surgical group. DualMesh Plus (ePTFE) (WL Gore & Associates, Newark, DE) was placed in the majority of these patients using both transfascial sutures and tack fixation. Fifty-eight patients had postoperative CTs of the abdomen and pelvis with ePTFE and known transverse diameter of the implanted mesh. The prosthesis was measured on the CT using the AquariusNet software program (TeraRecon, San Mateo, CA), which outlines the mesh and calculates the total length. Data were collected regarding the original mesh size, known linear dimension of mesh, seroma formation, and time interval since mesh implantation in months.

RESULTS

The mean shrinkage rate was 6.7%. The duration of implantation ranged from 6 weeks to 78 months, with a median of 15 months. Seroma was seen in 8.6% (5) of patients. No relationship was identified between the percentage of shrinkage and the original mesh size (P = 0.78), duration of time implanted (P = 0.57), or seroma formation (P = 0.074). In 27.5% (16) of patients, no shrinkage of mesh was identified. Of the patients who did experience mesh shrinkage, the range of shrinkage was 2.6-25%.

CONCLUSIONS

Our results are markedly different from animal studies and show that ePTFE has minimal shrinkage after LIVH repair. The use of transfascial sutures in addition to tack fixation may have an implication on the mesh contraction rates.

Intraobserver and interobserver reliability of two ultrasound measures of humeral head position in infants with neonatal brachial plexus palsy

BACKGROUND

Ultrasonographic evaluation of the hip in infants is considered both reliable and reproducible in the diagnosis of developmental dysplasia of the hip. Ultrasonographic evaluation of the shoulder in infants has been reported as a valuable diagnostic aid in dysplastic development following neonatal brachial plexus palsy. To our knowledge, there has been no study of the intraobserver reproducibility and interobserver reliability of sonography of the shoulder in infants with and without suspected posterior shoulder dislocation.

METHODS

Two identical but randomly ordered sets of the same deidentified sonographic images of shoulders in infants were given to radiologists, pediatric orthopaedists and orthopaedic residents, and fellows with varying degrees of experience in the evaluation of shoulder pathology in infants, who measured the position of the humeral head relative to the axis of the scapula. Intraobserver reproducibility and interobserver reliability of the measurements were assessed.

RESULTS

For the position of the humeral head with respect to the glenoid in both normal and abnormal conditions, the Pearson correlation coefficient for intraobserver reproducibility was 0.91 and the intraclass correlation coefficient for interobserver reliability was 0.875. For estimating the percentage of the humeral head posterior to the axis of the scapula, the Pearson correlation was 0.85 and the intraclass correlation coefficient was 0.77.

CONCLUSIONS

Ultrasonographic examination of the shoulder in infants to assess for the position of the humeral head with respect to the scapula showed high intraobserver reproducibility and interobserver reliability. It is recommended as a reliable technique for evaluating shoulder position in infants with neonatal brachial plexus palsy.

Volar ligament release and distal radius dome osteotomy for correction of Madelung's deformity

PURPOSE

Madelung's deformity is usually recognized near the completion of skeletal growth and corrective osteotomy of the radius is frequently performed to treat the deformity and reduce pain. This study reviewed the clinical and radiographic results of a volar approach, ligament release, and dome osteotomy technique for treatment of this deformity.

METHODS

Between 1990 and 2000, 26 wrists in 18 patients were treated with a volar ligament release and dome osteotomy of the distal radius. The average age of the patients at the time of surgery was 13 years. All patients were available for review at an average of 23 months after surgery. Radiographs before surgery and at final follow-up evaluation were analyzed for the extent of correction.

RESULTS

All patients treated with this corrective osteotomy reported a reduction in pain and improved appearance. Patients showed improvements in forearm supination and wrist extension, with no loss of pronation or flexion. Improvements in the radiographic parameters of radial inclination and lunate subsidence also were observed. Four wrists required concurrent ulnar-sided surgery, and 3 additional wrists required staged ulnar shortening. One patient required a Darrach resection 3 years after the index procedure.

CONCLUSIONS

The results of volar dome osteotomy provide improved range of motion, improved appearance, radiographic correction, and pain relief while preserving soft-tissue support for radial rotation around the distal ulna. Long-term follow-up evaluation is ongoing.

Vascularized bone grafting and herbert screw fixation of scaphoid nonunions with avascular proximal poles

Nonunion of the fractured scaphoid can present a difficult surgical problem, especially in fractures near the proximal pole. The incidence of nonunion is greater in this region, in which the vascularity of the proximal fracture segment is compromised and the proximal fragment is small and resists rigid fixation. Recent development of better vascularized bone grafting techniques has provided a tool with which to address this vexing problem. Because many authors had previously shown the advantage of rigid fixation in obtaining scaphoid union, it seemed advantageous to us to combine these two methods-rigid fixation and improved vascularity. In this article, we present in detail our technique for treating patients with very small proximal pole fractures in which the proximal fragment makes up less than 20% of the scaphoid. For practical purposes, all of these fractures have a proximal fragment that is avascular. We use a vascularized bone graft as described by Zaidemberg et al. in combination with more rigid fixation of proximal pole fractures using the Herbert mini screw. Although the technique presented requires the surgeon to use precise surgical technique, early results have been encouraging, and patients with very small fracture fragments can be treated successfully.

Forearm compartment syndrome in the newborn: report of 24 cases

PURPOSE

Isolated cases of ischemia, compartment syndrome, or Volkmann's ischemic contracture in the forearm of the newborn infant have been reported in the past. The purpose of this study is to review a large series of patients with neonatal forearm compartment syndrome and to report the important clinical features.

METHODS

A search of medical records from 1980 to 2000 identified 24 children with evidence of ischemia of the forearm at the time of birth. Records and images were reviewed for prenatal and birth history, maternal factors, medical conditions, pattern of involvement, treatment, and outcomes. Patients were grouped according to the extent of initial soft-tissue involvement.

RESULTS

All patients presented with a sentinel forearm skin lesion. Patterns of involvement ranged from mild skin and subcutaneous lesions to dorsal and volar compartment syndrome with or without distal tissue loss. Early treatment intervention was limited to a single case in which the diagnosis of compartment syndrome was made and an emergency fasciotomy was performed with a good outcome. In other cases tissue loss, compressive neuropathy, muscle loss, and late skeletal changes were responsible for impaired function. Distal bone growth abnormality was common.

CONCLUSIONS

Forearm compartment syndrome in the newborn is not as uncommon as previously thought. The skin lesion was the common, salient, initial diagnostic finding. Early diagnosis and appropriate referral led to the salvage of a functional limb in 1 of the patients in this series. The severity of the initial insult correlated with the degree of impairment in growth and function. The delayed diagnosis and treatment of an evolving compartment syndrome may compromise further final function.

Focal fibrocartilaginous dysplasia in the upper limb: seven additional cases

Focal fibrocartilaginous dysplasia is a benign bone lesion known to cause deformity around the knee in young children. Three cases affecting the long bones of the upper limb have been reported, and little is known of the natural history. This study reports seven more cases affecting the upper extremity. All patients presented with deformity in early childhood. The location was the radius in two, the ulna in three, the proximal phalanx in one, and the middle phalanx in one. The radiographic appearance of the condition is diagnostic, regardless of the bone it affects. Proportional shortening of the affected segment was present in all patients. The phalangeal cases had marked deformity and were osteotomized, with early recurrence of the deformity in one case. The forearm lesions did not all resolve spontaneously. In the two patients with 7-year follow-up, the length discrepancy increased from 0.5 cm to 2 cm and a degree of cosmetic deformity remained, without functional impairment. Ulna lesions place the radiocapitellar joint at risk for dislocation and should be observed for this complication.

Carpal wedge osteotomy for the arthrogrypotic wrist

The upper limbs of the child with the amyoplasia form of arthrogryposis are typically internally rotated at the shoulders, extended at the elbows, and flexed and deviated ulnarly at the wrists. This position results in an obligatory crossed-limb pattern of bimanual use, as neither hand is sufficiently strong or agile to function independently. A change in the position of deformity to one that allows the palms to come together without crossing the arms, and also allows access to desktops and keyboards, is a reasonable goal for children with this condition. A severe internal rotation deformity at the shoulder can be corrected with external rotation osteotomy, and elbow extension contractures can be released with soft-tissue procedures to increase the passive range of motion. However, most attempts to improve wrist position have been disappointing because they have resulted in the loss of any limited motion that might be present. This paper describes a technique of resection of a portion of the carpus that improves position and retains motion because it spares the radiocarpal joint.

Neonatal brachial plexus palsy. Outcome of absent biceps function at three months of age

BACKGROUND

An important prognostic factor in neonatal brachial plexus palsy is the time interval to biceps muscle recovery. Although the natural history is not clear, biceps muscle recovery after more than three months of age has been used to predict poor long-term shoulder function. The absence of biceps muscle function at three months of age has been adopted as an indication for early brachial plexus microsurgery, in an attempt to improve recovery. To provide a benchmark for outcome comparison, the long-term outcome of patients with absent biceps muscle function at three months of age was studied.

METHODS

Between 1980 and 1992, 170 patients with neonatal brachial plexus palsy were entered into a prospective study in which details of the birth and serial clinical examinations were recorded. Patients were grouped according to the level of injury and the time interval to biceps muscle recovery. Twenty-nine patients were observed to have absent biceps muscle function at three months of age. Twenty-eight of those patients were available for long-term followup at a mean age of eleven years and one month. At the time of follow-up, patients answered a questionnaire and underwent manual muscle strength testing, sensory evaluation, and grading of their shoulder function according to Gilbert's modification of the Mallet score, in which the function was graded as II, III, or IV with class I (no function) and V (normal) eliminated. The level of injury and the time that biceps muscle function returned were compared with the final outcomes.

RESULTS

The level of injury was C5-C6 in thirteen (46%) of our twenty-eight patients with absent biceps muscle function at three months of age, C5-C7 in five (18%), and pan-plexus (C5-T1) in ten (36%). Biceps contraction was observed by six months of age in twenty patients (71%), including all thirteen patients with a C5-C6 level of injury. Twenty-two patients did not have surgery on the brachial plexus, but nine of those patients had subsequent orthopaedic procedures. At the time of follow-up, twenty-seven of the twenty-eight patients had at least antigravity biceps muscle function. Patients who regained biceps muscle function between three and six months of age had better scores for abduction (p = 0.04) and for hand-to-neck (p = 0.05) and hand-to-back (p < 0.001) function than did patients who regained biceps muscle function after six months of age. Patients with a C5-C6 lesion had better scores for external rotation (p = 0.04) and for hand-to-neck (p = 0.05), hand-to-mouth (p < 0.01), and hand-to-back (p < 0.001) function than did patients with a pan-plexus lesion. Twelve (55%) of the twenty-two patients who did not have brachial plexus surgery had a class-IV shoulder (good function) according to the modified Mallet score. Of the twelve patients with a C5-C6 level of injury who did not have brachial plexus surgery, eight had a class-IV shoulder.

CONCLUSIONS

This study indicated associations between prolonged neurological recovery and a more extensive level of injury and worse long-term shoulder function. Patients with a C5-C6 injury and absent biceps muscle function at three months of age often have good long-term shoulder function without brachial plexus surgery.

Keloid formation after syndactyly reconstruction: associated conditions, prevalence, and preliminary report of a treatment method

PURPOSE

The purpose of this study is 3-fold: to review our cases of keloid formation after syndactyly release, to report a clinical association between primary enlargement of the digits and risk of keloid formation, and to report treatment using low-dose, short-term methotrexate as an adjunct to revision surgery.

METHODS

A retrospective review of patients identified with keloid formation after syndactyly reconstruction showed associated enlargement of the involved digits. A search of medical records for cases in which both syndactyly and digital enlargement occurred was carried out. Charts and images, where available, were reviewed for information about age, gender, involved site, associated conditions, and treatment.

RESULTS

Eight cases of keloids occurred in 1004 surgical procedures in 681 patients carried out during the 20-year period reviewed. Seven patients were white and 1 was Hispanic. Seven of the 8 had associated primary digital enlargement. Two patients who had enlarged syndactylized digits did not develop keloids after surgery. There was no family history in any case. Standard treatment (pressure, topical or intralesional corticosteroids, and re-excision) was unsuccessful in resolving the keloids. Two children treated with adjunctive methotrexate had successful treatment of their keloids and near-normal healing. Length of follow-up time after the last treatment ranged from 6 months to 11 years (average, 5.5 years).

CONCLUSIONS

Primary digital enlargement is highly predictive of risk of keloid formation after syndactyly reconstruction. Very-low-dose, short-term methotrexate was successful as an adjunct to surgical treatment in 2 cases.

The embryogenesis of the specialty of Hand Surgery: a story of three great Americans--a politician, a general, and a duck hunter: The 2002 Richard J. Smith memorial lecture

Although the origins of surgery of the hand come from many different countries over several decades, the specialty of Hand Surgery is uniquely American and came out of the experience of the US Army Medical Corps Hand Centers during and immediately after World War II. The circumstances and opportunities that allowed for the development of the specialty, however, were set in motion years before the war. It is a story of friendship, opportunity, ingenuity, and commitment. That embryogenesis of hand surgery was the result of the intersection of the lives of 3 great Americans--President Franklin Delano Roosevelt, Surgeon General of the Army Norman T. Kirk, and Dr. Asa Sterling Bunnell. These men led fascinating lives and each had personal motivations that made it possible for the specialty to flourish.

Treatment of Kienbock's disease with capitohamate arthrodesis: pain relief with minimal morbidity

Despite the large number of procedures available for treatment of Kienbock's disease, no single method has emerged as being clearly superior. Ultimately, the goal of treatment must be the relief of pain and maintaining wrist range of motion. The authors' experience with 45 consecutive wrists that had undergone capitohamate fusion for treatment of Lichtman's stage 1, 2, or 3 Kienbock's disease is presented. Average follow-up was 32 months (range, 4 to 107 months). All arthrodeses healed with an average time to fusion of 1.9 months. Postoperatively, 93 percent of patients had either no pain or less pain than they had preoperatively, with preservation of wrist range of motion and improved grip strength (52 percent of normal preoperatively to 72 percent of normal postoperatively). The authors conclude that capitohamate arthrodesis relieves pain in 93 percent of patients with stage 1, 2, or 3 Kienbock's disease and is an effective treatment for this disease.

The Littler line method and the area under a Gaussian curve: a new method of assessing digital range of motion

A new method of measuring digital range of motion (the Littler line method) is presented. When a Gaussian curve is centered over the Littler line and the appropriate area under the curve is computed, this area can provide a measure of the functional range of motion regained by an injured digit. Seventeen children (24 digits) with flexor tendon injuries were evaluated at an average follow-up period of 58 months (range, 12-121 months). The Littler line/Gaussian curve method was found to be more reproducible than total active motion, particularly in zone I and II injuries. This method can serve as a more meaningful functional assessment tool than a linear measurement such as total active motion, because it emphasizes digital motion in the mid-ranges of digital motion.

Madelung's deformity. Surgical correction through the anterior approach

A resurgence of interest in Madelung's deformity has developed recently because of improved operations for correction of the deformity, identification of the genetic loci for the condition in certain syndromal variants, identification of an anterior ligamentous structure tethering the carpus, and preventive treatments in growing children. The process is reviewed in this article and a new surgical technique is presented. The procedure is performed by way of an anterior incision that is more cosmetically appealing. The release of an anterior ligamentous structure described by Vickers is performed simultaneously with a dome shaped osteotomy of the radius. The fragments, once alignment is corrected, are stablized with temporary pin fixation and a long arm cast until the bone has healed.

The spectrum of presentation of silent sinus syndrome

The general clinical, ophthalmologic, and radiologic features of three patients with silent sinus syndrome are presented. All three patients were treated surgically. The cases of these patients illustrate the spectrum of presentation of silent sinus syndrome, including enophthalmos, hypophthalmos, transient vertical diplopia, lid retraction, lagophthalmos, and blurred vision. All patients had sinus disease, and all patients improved after surgery using functional endoscopic sinus surgery techniques. The protean manifestations of silent sinus syndrome can be identified, thereby allowing appropriate management.

Trigger finger in children

At the Texas Scottish Rite Hospital for Children, 239 trigger digits in 176 children were seen and treated surgically over a 10-year period. Trigger fingers accounted for 33 (14%) of these digits in 18 (10%) of the patients. In 8 of 18 patients (44%) the fingers continued to trigger after A-1 pulley release. In children, trigger fingers are different from trigger thumbs. Trigger fingers in children are uncommon and have variable causes, and an A-1 pulley release alone will not always correct the triggering. Additional treatments, such as resection of one or both limbs of the sublimis tendon or an A-3 pulley release, may be required. An awareness of other contributing factors and readiness to explore the entire flexor mechanism should help prevent failure of surgical treatment.

Open reduction and internal fixation of unstable distal radius fractures with a low-profile plate: a multicenter study of 73 fractures

A study of acute, dorsally displaced, unstable (high-energy) fractures of the distal radius was conducted to determine the safety and efficacy of a new low-profile plate for unstable distal radius fractures. Thirteen surgeons in 11 US cities participated in the study. A minimum follow-up period of 1 year was required to be included in the study. Seventy-three fractures in 71 patients met this criterion. Each fracture was treated according to a prospective protocol. An autogenous bone graft was used in 64 fractures. All procedures were completed using a radiolucent sterile traction table. No external fixators were used either during or after the operation. After bone grafting and while in traction, a fracture reduction clamp with a template preshaped to the normal contour of the dorsal radial metaphysis molded the fracture into reduction and then allowed precision drilling of the holes for the plate. Active wrist motion began at an average of 14 days. Satisfactory open reduction was obtained in 93% of the fractures and maintained in 88%. Ninety-five percent of the fractures demonstrated good or excellent outcomes using a standardized evaluation. Eighty-one percent of the outcomes were rated as excellent. This initial report demonstrates that the method is a safe and effective treatment for acute, unstable, dorsally displaced fractures of the distal radius.

Iliac crest bone grafting and Herbert screw fixation of nonunions of the scaphoid with avascular proximal poles

Between 1989 and 1991, 137 nonunions of the scaphoid were treated by the senior author, who noted that 26 of these nonunions had an avascular proximal pole (no punctate bleeding from the bone at the time of surgery). All 26 nonunions were treated with iliac crest bone grafting and Herbert screw fixation. Of these 26 patients, 17 were followed for more than 1 year after their surgery (average follow-up period, 31 months). The average time from injury to surgery was 31 months. Of the 17 patients included in this study, 12 were treated with a palmar approach to the nonunion, 5 with a dorsal approach. The 12 nonunions that occurred at either a midwaist or distal location were approached through a palmar modified Russe incision and treated with interpositional corticocancellous iliac crest bone graft in addition to the Herbert bone screw. The five nonunions with a very small proximal fragment were approached through a dorsal incision and treated with cancellous iliac crest bone graft and Herbert screw fixation. All patients were immobilized after operation in a short-arm thumb spica cast for 3 months and were then allowed active range of motion of their wrists. Return to full activity was permitted once preoperative wrist motion was restored. Radiographic union, as defined as bridging trabeculae of bone present in all x-ray films, occurred in nine patients, an incomplete union or persistent fibrous union in seven, and a nonunion in one patient. Using the scaphoid outcome score, an assessment scale based on pain, occupation, wrist motion, strength, and patient satisfaction, functional results were graded as excellent in six patients, good in five patients, fair in four patients, and poor in two patients. The average range of motion of the wrist did not significantly improve after surgery, but the average grip strength of the injured hand increased by 29 lbs. There were no intraoperative complications. However, three patients required further operative procedures including radial styloidectomy, pin removal, and carpal tunnel release. No patient has required either a proximal row carpectomy or wrist arthrodesis. Previously published results of avascular proximal pole scaphoid nonunions suggest that union cannot be obtained and functional results are uniformly poor. In contrast, the functional and x-ray results of our patients are markedly improved over these previous studies--emphasizing the importance of iliac crest bone grafting, rigid internal fixation, and appropriate postoperative immobilization.

Injection injuries to the median and ulnar nerves at the wrist

Carpal tunnel syndrome is often treated nonoperatively with temporary wrist immobilization and local steroid injections. A direct injection into a peripheral nerve can result in permanent damage. Two cases of median nerve injection injury and one involving the ulnar nerve are presented; all were treated with neurolysis and debridement of the injected material. At follow-up ranging from 1 to 11 years, all patients showed significant improvement, but with some functional loss. The literature is confusing because of the variety of injection techniques used for the treatment of carpal tunnel syndrome, some of which put the median nerve at risk. We recommend that the injection be made midway between the palmaris longus tendon and the flexor carpi ulnaris tendon just proximal to the proximal edge of the transverse carpal ligament in a line with the superficialis tendon of the ring finger. The injection should be stopped and redirected if the patient experiences paresthesia of any kind.

The pulp plasty: a composite graft for complete syndactyly fingertip separations

Composite grafts of skin and subcutaneous fat harvested from the glabrous non-weight-bearing areas of the foot were used to graft 34 fingertips after separation of 23 complete syndactyly webs in 13 patients. Simple complete syndactylies accounted for 17% and complex complete syndactylies accounted for 83%; synonychia was encountered in 70%. Follow-up averaged 13.9 months (minimum, 2 months, maximum 33 months). All patients had 100% take of the composite graft. Subjective gradings were 94% good, 6% fair, and there were no poor results. This technique provides a relatively normal contour and satisfactory pad to the fingertip.

The scaphoid allograft: a new operation for treatment of the very proximal scaphoid nonunion or for the necrotic, fragmented scaphoid proximal pole

This is a preliminary report of eight cases in which an allograft was used to replace half of the scaphoid. The indications for the procedure include the following: (1) Severe necrosis with fragmentation of the proximal pole, (2) Very proximal pole nonunion with small (less than 20% of the bone), unreconstructable proximal fragments, and (3) One case of severely comminuted intra-articular fracture of the scaphotrapezial joint and basal joint of the thumb caused by a gunshot wound. The Herbert scaphoid screw was used to provide rigid fixation. Follow-up ranged from 8 to 30 months. The result was good in six of eight patients. It should be emphasized that this is a preliminary report of the early experience with a new operation for salvage of difficult scaphoid fracture problems.

Silicone rubber carpal implants: a study of the incidence of late osseous complications

This clinical review of 53 silicone rubber carpal implants done by the senior author (P. R. C.) between 1976 and 1983 determines the incidence of so-called "silicone rubber synovitis." Although previously reported in small series, the true incidence of this complication of wear of the implant has not been documented. In this study late radiographic follow-up demonstrated lytic lesions adjacent to the carpal implants in 75% of the scaphoid implants, 55% of the lunate implants, and 75% of the scapholunate implants. In patients with x-ray film evidence of lytic lesions, more than half (56%) complained of pain, and more than one fourth (27%) have already had revision surgery. In every patient who had reoperation in this study, the histologic examination of the tissue in the wrist showed a chronic granulomatous process identical to that previously reported in cases of so-called "silicone rubber synovitis". These "lytic lesions" must be differentiated from "degenerative cysts" that are a part of the natural progression of degenerative arthritis. Four cases were submitted for mass spectrophotometric analysis, and the positive identification of the silica atom was made in all four. This study shows that the wear of carpal bone implants of silicone rubber and subsequent "silicone rubber synovitis" are common occurrences and not rare as has been previously inferred from isolated case report studies. This study suggests that implantation of these implants in young, healthy individuals is rarely indicated, and careful follow-up of patients who already have these implants in place is important.(ABSTRACT TRUNCATED AT 250 WORDS)

Injuries to the major nerves of the hand

This article outlines methods that can be used in the emergency department or in the physician's office to establish the presence of injury to a peripheral nerve in the upper limb. This includes motor and sensory tests that require equipment no more sophisticated than a paper clip but that give accurate, reproducible, clinically useful information.

Crush injury of the upper limb. Early and late management

The care of the patient with a crushed upper limb requires accurate assessment, carefully planned and executed surgical procedures, diligence, and reassessment. Often, a long period of rehabilitation is also needed. The quality of care rendered by the surgeon and therapist often affects the patient's functional end result and his chance to regain his ability to provide for himself independently.

Ununited fracture of the hook of the hamate

Of nine ununited fractures of the hook of the hamate, eight were treated by surgical excision of the fragment. All eight patients had relief from persistent pain and regained the preinjury level of function. This fracture occurs frequently in athletes and is often not diagnosed because it can be demonstrated only by special roentgenographic views. It is concluded that this fracture may be less rare than is commonly believed and that surgical excision permits early return of function, especially in athletes and laborers who must be able to grip hard objects strongly.
