Surgical treatment of partial and full distal biceps tendon ruptures.

This study presents a series of cases with surgically treated partial distal biceps tendon ruptures. The results of full distal biceps tendon rupture repair are also presented and a comparison is made between the two groups. Between 2001 and 2015, patients with partial and full ruptures of the distal biceps tendon were surgically repaired. At follow-up, the elbow function of the patients was assessed using the Oxford Elbow Score and maximum flexion and supination forces were measured. Forty-eight elbows in 43 patients returned to the follow-up visit. There was no statistically significant difference between the two groups in terms of function and strength. In this study, there were no statistical differences in outcome between the partial and the full distal biceps tendon groups. Surgical repair seems to be a valuable treatment option for partial distal biceps tendon ruptures.

Myositis ossificans circumscripta of the triceps due to overuse in a female swimmer.

Myositis ossificans is a rare condition characterized by non-neoplastic heterotopic bone formation in soft tissue and skeletal muscle. It is a benign and often self-limiting disease with no need for surgery. Here, we describe a young female swimmer with myositis ossificans circumscripta of the triceps due to overuse. Because of the benign character of the lesion, conservative treatment was initiated with rest and anti-inflammatory drugs. She obtained complete resolution after 6 months and was able to return to normal sporting activities. Myositis ossificans circumscripta is a rare benign lesion with an excellent prognosis. Most lesions in athletes occur due to contusions or strains; however, overuse is now described as well. Spontaneous resolution is seen in almost all cases. Cases in which, despite conservative treatment, a painful mass persists, surgical excision can be considered.

A 3D-CT scan study of the humeral and glenoid planes in 150 normal shoulders.

PURPOSE: The purpose of the study was to determine the normal three-dimensional relationship between the humeral and the glenoid plane of the individual patient. We measured the three-dimensional angle between the glenoid plane and the humeral plane (glenohumeral angle, °GH) and the angle between the plane of the scapula and the plane of the glenoid (glenoscapular angle, °GS) with the patient in a standardized position to the CT scan gantry. We hypothesized that a normal distribution with a small variation would exist for both angles. METHODS: A total of 150 conventional CT scans of normal shoulders from patients aged between 18 and 80 years were examined and three-dimensional reconstructions were derived from it. The descriptive statistics and the variability of °GH and °GS were determined. RESULTS: The mean °GH was 57.9°, and the mean °GS was -3.77°. The overall reliability of the measurement was good. Descriptive statistics of this study confirm the normal distribution and a narrow variation of both parameters. CONCLUSIONS: This is the first study to determine the normal 3D relationship between the humerus and the glenoid (°GH). This new three-dimensional anatomical information of the normal glenohumeral relationship and glenoid can be used to distinguish normal from pathological anatomy, as well as alternative surgical guidance especially in bony deficient glenoids.

Multiple tibial insufficiency fractures in the same tibia: a case report.

Stress fractures were first described by Briethaupt in 1855. Since then, there have been many discussions in the literature concerning stress fractures, which have been described in both weight-bearing and non-weight-bearing bones. Currently, the tibia is the most frequent location, but multiple stress fractures in the same tibia are rare. This paper presents an unusual case of a 60-year-old woman with multiple tibial stress fractures of spontaneous onset.

Functional and radiological outcome after arthroscopic and open acromioclavicular stabilization using a double-button fixation system.

The aim of this study was to determine the functional outcome and radiological results after open and arthroscopic stabilization of the acromioclavicular joint using a double-button fixation system. We reviewed 16 patients that were surgically treated for acromioclavicular dislocation using a double-button fixation system. An arthroscopic technique was used in 9 patients for acute injuries and an open technique in 7 patients for subacute or chronic lesions. Mean follow-up was 17 months (range : 6-26 months). The mean DASH score post-operatively was 2.29 (range : 0-5.83), VAS score was 0.82 (range : 0-2) and SSV averaged 90.5 % (range: 80-95%). Radiologically the reduction of the acromioclavicular joint was complete in 10 patients. A clinically stable residual subluxation was present in 5 patients. Only one patient experienced a redislocation after new trauma and needed revision surgery. Operative treatment of grade 3 and 4 acromioclavicular dislocations, using a double button coracoclavicular fixation system, yielded good functional results with full return to work and recreational activities. Arthroscopic coracoclavicular fixation without CA ligament transfer should be reserved for acute injuries within 2 weeks after the trauma.
