The severity of the impingement syndrome affects the diagnostic values of the commonly used clinical tests. The variable accuracy of these tests should be taken into consideration when evaluating patients with symptoms of rotator cuff disease.

In patients with rotator cuff abnormality, the diagnosis of partial biceps tears cannot be made reliably with existing physical examination tests. Diagnostic arthroscopy is recommended, if clinically indicated, for potential partial tears of the long head of the biceps tendon. The treating physician should be prepared to treat unsuspected tears of the long head of the biceps tendon at the time of surgery.

The pathology of congenital pseudoarthrosis of tibia is an enigma and the treatment is challenging. Despite achieving union of the pseudoarthrosis, these patients may have compromised function secondary to residual deformities. The purpose of this study is to analyze the prevalence of these deformities, the morbidity caused by them, and the methods to overcome the problems. Sixteen patients who had a successful union were retrospectively reviewed. Clinically, the following parameters were assessed: pain, joint stiffness, and limb length discrepancy (LLD). Anteroposterior and lateral lower extremity radiographs were performed to analyze (1) union of the tibia and fibula, (2) deformity of the tibia, (3) degree of ankle valgus, (4) degree of calcaneus of the os calcis, (5) LLD, and (4) refracture. The average follow-up was 16 years from the first and 8 years from the last surgical procedure. Residual deformities included valgus of tibia (average 11.4 degrees) and procurvatum (average 19.4 degrees) deformities of the tibia or valgus deformity of the ankle (average 21.3 degrees) and calcaneus of the os calcis (average 46 degrees). There were 9 refractures in 8 patients. Nine patients had an LLD (average 3.5 cm). The study demonstrates that careful follow-up of these patients is necessary and residual problems are to be treated as they occur.

The authors review their experience with four patients with congenital deficiency of the anterior cruciate ligament (ACL) who underwent surgical treatment of symptomatic knee instability at a mean age of 15.8 years (range 14-17 years). Associated syndromes included fibular hemimelia, congenital short femur, and an unspecified skeletal dysplasia. All patients had undergone multiple previous realignment and leg lengthening procedures and were skeletally mature at the time of the reconstruction. All four patients underwent ACL reconstruction, and one patient underwent concomitant posterolateral corner reconstruction. One patient required an osteochondral autograft transplant procedure in addition to ACL reconstruction. Hypertrophy of the meniscofemoral ligament of Humphrey was a consistent anatomic finding at surgery. The patients were followed for a mean of 38 months (range 26-58 months) after the reconstruction. The mean preoperative Lysholm II score was 38 (range 28-56); the score had improved to a mean of 81 (range 78-93) at the latest follow-up. The authors conclude that reconstructive surgery is a viable option for restoration of knee stability and function in appropriately selected patients with congenital ACL deficiency.

We describe a new surgical technique for the treatment of de Quervain tenosynovitis, which consists of lengthening the first dorsal compartment without disruption of continuity and without using a suture. Our results in 12 wrists operated on in 10 patients indicated complete relief of symptoms. The advantages of the technique include: simplicity, restoration of normal anatomy, and prevention of complications (scarring, adhesions, and subluxation of tendons).

Proximal humerus fracture is a common orthopedic presentation, with bimodal age distribution. On the other hand, bilateral proximal humerus fracture dislocation is a rarely reported pathology, especially when it is not the result of direct trauma. We present a case of a 71-year-old female patient found to have simultaneous bilateral 4-part proximal humerus fractures following status epilepticus treated surgically with bilateral reverse shoulder arthroplasty with constraint and soft tissue release. In a patient with recurrent status epilepticus episodes, the combination of constrained reverse shoulder arthroplasty and the extensive soft tissue release should decrease the rate of failure and dislocation dramatically. We conclude, after reviewing the literature, that there is no straightforward algorithm for treating such patients and that a clear classification should take into account both bone quality and patient comorbidities which has yet to be developed.

Recurrent capsular laxity after failed thermal capsular shrinkage is common and frequently associated with capsular thinning. In most instances, the capsule quality does not appear to technically affect the revision procedure.
