Background:We report the functional impact and natural history of cutaneous hypoesthesia after plate internal fixation for mid shaft clavicle fractures with a horizontal skin incision from year 2009 to 2011.Materials and Methods:38 patients had complete followup data with an average followup period of 23.2 months (range 8-43 months). The impact of supraclavicular nerve injury was studied by assessment of the incidence, functional impact and natural history of numbness with detailed review of the case records and phone questionnaires.Results:The incidence of postoperative numbness was 55.3% (n = 21). Most patients reported the numbness to be at its worst within the first operative month. At the time of worst numbness, 28.6% (n = 6/21) of patients reported the numbness to be severe while 42.9% (n = 9/21) reported moderate numbness and 28.6% (n = 6/21) reported mild numbness. Fifteen of these patients described increased awareness of numbness during contact with straps or clothes. Two patients were significantly bothered by this numbness; 4 patients stated that it was a moderate bother while 7 patients considered it a mild bother. A total of 8 patients reported that they were not bothered at all by the numbness. An overwhelming majority of affected patients (90.5%, n = 19/21) reported an improvement in the severity of numbness felt over time. At the last followup, the incidence of numbness declined from 55.3% to 36.8% with 7 patients reporting complete resolution of numbness. The numbness however was found to persist in 66.7% of patients. Only 1 patient reported continued severe numbness. The awareness of numbness with straps and clothing was severe in 5 patients. None of the patients were significantly bothered by this numbness.Conclusions:Cutaneous sensory loss is a common occurrence following plate fixation of the clavicle and might have been under reported in the literature. The numbness improves in the vast majority, but commonly persists to some degree for up to 2 years and maybe permanent. However, only a small minority eventually considered the numbness a significant “bother” and to affect them while wearing clothing or when in contact with shoulder straps.

Ganglion cysts originating from the anterior cruciate ligament (ACL) are uncommon. Often asymptomatic, they infrequently present with non-specific symptoms such as knee pain, stiffness, clicks, locking or restriction of knee extension. However, the patient we report presented with knee flexion restriction. A 37-year-old Chinese gentleman, with no history of knee trauma, presented with left knee pain. Left knee range of motion (ROM) was from 0 to 110 degrees. Magnetic resonance imaging (MRI) scan revealed a 1.5 cm × 3.3 cm × 1.7 cm cyst located in the intercondylar region arising from the ACL and extending predominantly posteriorly.Arthroscopy confirmed an intrasubstance ACL ganglion cyst, which was extending posteriorly. Complete excision of the cyst was performed. At 1-year follow-up, the patient regained knee flexion of 130 degrees. We describe one of the largest ACL ganglion cysts. Such cysts often extend anteriorly and impinge onto the roof of the intercondylar notch during knee extension, thus restricting extension. The restriction in knee motion in our patient was in flexion instead; this was because the cyst took an unusual course of extension predominantly in the posterior direction. Although rare, it must be included as a possible differential diagnosis when patients present with such knee symptoms.

Our review suggests that total elbow arthroplasty can give good to excellent short term results when used in the treatment of distal humerus fractures in elderly Asian patients.
