Surgical Treatment of Monteggia-Like Lesions With a Modified Boyd Approach

Introduction

Monteggia-like lesions are rare injuries in adults that include a wide spectrum of complex fracture-dislocations of the proximal ulna and radius. In this retrospective study, we performed a modified Boyd approach and a standard surgical protocol for the treatment of these lesions. Our aim was to evaluate the results of the operative treatment for patients with Monteggia-like lesions, using a modified Boyd approach.

Materials and Methods

We present a retrospective study of 14 patients who underwent surgical treatment for Monteggia-like lesions. Preoperative clinical and radiological evaluation was performed. In 5 cases radial head prosthesis was placed, and in 3 cases the radial fracture was stabilized with the use of interfragmental screws. Regarding the proximal ulnar fracture, ORIF-anatomical plate and ORIF-straight plate was used in 12 and 2 cases, respectively.

Results

Average clinical follow up was 16.9 months. Postoperatively, the mean Mayo Elbow Performance score was 83.4 points (range 70-100) and the mean visual analog scale was 1.7 (range 0-14). Mean flexion and loss of extension were 122.1° (range 80°-140°) and 21.4° (range 5°-40°), respectively. Mean supination of the forearm was 66.8° (range 50°-80°) and the mean pronation was 67.5° (range 60°-75°). Heterotopic ossification was observed in 3 patients (21.4%) and 1 patient developed stiffness (7.1%). The patient who developed stiffness underwent reoperation for plate removal and arthrolysis, with satisfactory results.

Conclusions

The surgical treatment of Monteggia-like lesions in adults remains a challenge. In the present study, the use of a standard surgical protocol, with a modified Boyd approach, successfully restores the movement and stability of the elbow, with a low complication rate.

Reverse Shoulder Arthroplasty for Failed Operative Treatment of Proximal Humeral Fractures

Introduction

Failure after operative treatment of complex proximal humeral fractures (PHF) can prove challenging even for experienced surgeons. Reverse shoulder arthroplasty (RSA) seems to offer a satisfactory revision procedure with good clinical outcomes.

Materials and Methods

We present a case series of 14 patients, who were treated during a 3.5 years period (from 01/2016 until 06/2019). They all underwent revision surgery with RSA for failed operative treatment of PHF. Their mean age was 68 years (range, 51-84 years). 2 patients (14.3%) had been primarily treated with open reduction and internal fixation (ORIF), 5 patients (35.7%) with hemiarthroplasty, 3 patients (21.4%) with closed reduction and percutaneous fixation and 4 patients (28.6%) with transosseous suture fixation (TSF). We evaluated their absolute Constant score (CS), Visual Analogue Scale (VAS) score, and Range of Motion at their final follow-up, and we made a full clinical and radiological assessment to detect any postoperative complications.

Results

The mean absolute CS, VAS score, active anterior elevation, active abduction significantly improved compared with the preoperative status. Less significant difference was found in external rotation when comparing with the preoperative status (P = .0304). No significant differences were found when comparing RSA for different failed primary techniques (P > .05). No complications were detected following the revision surgeries of all patients.

Conclusion

RSA is an appropriate treatment as a revision technique for failed primary surgical treatment of PHFs. Though challenging it can offer good clinical results and pain relief.

Excisional Arthroplasty for Isolated Scaphotrapeziotrapezoidal Arthritis with the Use of Palmaris Longus Tendon

Background: Isolated scaphotrapeziotrapezoidal (STT) joint osteoarthritis (OA) is a relatively common condition. Scaphotrapeziotrapezoidal arthrodesis is the traditional treatment, while excisional arthroplasty with the use of flexor carpi radialis (FCR) or polycarbon implants represents a promising alternative surgical management. The present study aims to assess a novel alternative technique of excisional arthroplasty with the use of palmaris longus (PL) tendon as interposition material. Materials: The present research is a retrospective observational study. Patients suffering from symptomatic isolated STT OA, without midcarpal instability and treated with excisional arthroplasty with the use of PL tendon as interposition material, were evaluated. Five patients (two males and three females) with mean age of 63.8 years [standard deviation (SD)=16.9] were included. The mean follow up was 56.4 months (SD=9.8). In order to quantify the clinical results, we used the preoperative and postoperative visual analogue scale (VAS) score at rest and during activity, abbreviated Disabilities of the Arm, Shoulder and Hand (QuickDASH) score and postoperative ROM. Results:The postoperative VAS score at rest and during activity showed a decrease of 86.2% and 62.5%, respectively, when compared to the preoperative one. Regarding postoperative ROM at final follow-up, patients had a mean wrist flexion 71° compared to 78° of the contralateral hand, while the mean extension was found to be 57° compared to 66° of the contralateral side. Conclusions:The evaluated novel technique with the use of PL tendon as interposition material seems to offer satisfying results, while allowing to keep the FCR tendon intact. More studies comparing these techniques are of utmost importance to conclude which is the optimal treatment.

A Case of Reconstruction of a Type IIIc Open Tibial Fracture with Bone Loss and Warm Ischemia Time of 13 Hours: Quality of Life and Review of the Literature

BACKGROUND The management of open Gustilo IIIC fractures can be challenging even for experienced orthopedic surgeons. The decision between limb salvage and amputation is extremely difficult and the scoring systems do not seem to affect it significantly. Although ischemic time has been proven to be a major factor, attempts at reconstruction of limbs with ischemic time over 6 hours have been made in past decades. A simultaneous management of skeletal, soft-tissues, and vascular injury should be performed. This requires an orthoplastic surgeon who is capable of doing all the necessary operations by him/herself with hand-surgery and microsurgery expertise. CASE REPORT We present a case of a 49-year-old man with a type IIIC open tibial fracture with bone loss and warm ischemia time of 13 hours, who underwent revascularization and reconstruction with good radiological and functional results after a follow-up of 3 years. A few similar cases have been presented in the literature but none of them had a combination of bone loss, severe soft tissue injury, and complete vascular disruption after a crush injury. CONCLUSIONS The treatment of type IIIC open fractures of the tibia can be a demanding and time-consuming process. Detailed information about the necessity of multiple surgical interventions must be explained and fully understood by the patient in order to have realistic expectations.

Reconstruction of elbow flexion with a modified Oberlin procedure: A comparative study

INTRODUCTION

In upper brachial plexus injuries (C5-C6-C7), selective nerve transfers appear as a favourable technique. For this purpose, transfer of an ulnar nerve fascicle to the biceps motor branch (Oberlin's procedure) is often used. In this paper we present our modified Oberlin technique, as well as a comparison of this method with the classic Oberlin procedure.

MATERIALS AND METHODS

We present two groups of patients that where operated by two different surgeons. The first group, consisting of 16 patients was treated with the classic Oberlin procedure. The second group included 5 patients treated with a modified Oberlin procedure, where two fascicles from the ulnar nerve were transferred to both the motor branch of the biceps and the motor branch of the brachialis muscles.

RESULTS

In the last follow-up of the 16 patients from the first group with the classic Oberlin procedure, 15 patients (93.75%) had Medical Research Council (MRC) grade of biceps strength 4 and 1 patient (6.25%) had MRC grade 3, whereas in the group where the modified Oberlin procedure was used the muscle strength was very durable with 4 out of 5 the patients reached MRC grade of 4+ and one MRC grade of 4, and with a mean elbow strength at 5.4 kg (3-8 kg). No sensitivity or motor problems were encountered on the ulnar territories for both groups.

CONCLUSION

With the modified Oberlin technique, the median nerve is reserved and both elbow flexors are innervated. The results of this technique compare favourably with those of other methods. Thus, we propose using the double fascicle transfer from the ulnar nerve to both elbow flexors in order to restore a strong elbow flexion in patients with upper brachial plexus injuries.

Characteristics and diagnostic workup of the patient at risk to sustain fragility fracture

The human body undergoes several physiological adaptations as a result of the aging process. Amongst other organs, the skeleton is also affected and when bone fragility is present, an increase in both morbidity and mortality has been reported. Identification of risk factors to calculate the probability for a given patient to develop a fragility fracture it is therefore of paramount importance. Moreover, the existence of an in house protocol for diagnostic work up using biochemical tests and imaging investigations is essential. In the herein study we discuss a diagnostic protocol that has been developed in our clinic based on knowledge from the literature and our clinical experience.
