RESUMEN

Background Perilunate dislocations and perilunate fracture dislocations (PLDs/PLFDs) are rare and often associated with poor outcomes. Heretofore, these outcomes have not been evaluated in a high-demand military population. Questions/Purpose The purpose of this study was to evaluate the outcomes in a young, active population after sustaining PLD/PLFD injuries. Patients and Methods We retrospectively reviewed the U.S. military service members who underwent surgical treatment for a PLD/PLFD (Current Procedural Terminology codes 25695 and 25685) between June 1, 2010, and June 1, 2014 through the Military Health System Management Analysis and Reporting Tool (M2) database, capturing patients with a minimum 2-year follow-up. Patient characteristics and outcomes were gathered; however, radiographic analysis was not possible. Results In this study, 40 patients (40 wrists) were included with an average follow-up of 47.8 months. The average age was 28.8 years. Twenty-two injuries (55%) were PLFD and 22 (55%) cases involved the nondominant extremity. On initial presentation, 11 (27.5%) were missed and 50% of patients were presented with acute carpal tunnel syndrome. Range of motion (ROM) was 74% and grip strength was 65% compared with the contralateral wrist; 78% reported pain with activity and only 55% remained on active duty status at final follow-up. Injuries to the nondominant extremity were significantly more likely to experience a good to excellent outcome and regained a more ROM. Patients with ligamentous PLD had less pain at rest and were more likely to return to sport. Conclusion Worse outcomes can be expected for PLD/PLFD of the dominant extremity, transscaphoid PLFD, greater arc injuries, and those undergoing pinning alone. A high-demand patient may expect worse functional results with a higher degree of limitation postoperatively. Level of Evidence The level of evidence is therapeutic IV.

RESUMEN

BACKGROUND: Trigger finger is a relatively common clinical entity. The etiology is most often attributable to stenosing tenosynovitis though traumatic cases have been described. When trigger finger is associated with an underlying flexor tendon rupture, previous cases have reported a clear association with overt laceration or previous trauma. METHODS: We present the case of a 23-year-old male active duty military service member who presented with a characteristic history and clinical exam consistent with trigger finger. The symptomatic onset was gradual, with no history of inciting trauma. RESULTS: Given symptomatic persistent triggering following failure of conservative management to include cortisone injections, the patient was taken for open A1 pulley release. Intraoperatively, the triggering was found to be attributable to a partial attritional rupture of the small finger flexor digitorum profundus tendon. Tendon debridement, tubularization, and A1 and partial A2 pulley releases were performed with subsequent resolution of triggering. CONCLUSION: We present the rare case of subclinical atraumatic attritional rupture of the FDP tendon to the small finger as a cause of clinically apparent trigger finger. This is an important consideration as the hand surgeon must be prepared to address more atypical pathologies.

RESUMEN

PURPOSE: Radial head arthroplasty (RHA) is a viable treatment for complex radial head fracture. Whereas elbow stability and function is typically restored at short- to mid-term follow-up, the outcome in higher-demand populations is not well defined. We sought to characterize the functional and occupational outcomes following RHA in an active duty military population with intense upper extremity demands. METHODS: We retrospectively reviewed the records of all U.S. military service members undergoing primary RHA from 2010 and 2013 with a minimum of 2-year follow-up. Patient-based, injury-related, and surgical variables were extracted from the military-wide electronic medical record. Functional and occupational outcomes including pain, and Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire were recorded. The primary outcomes of interest were the rate and level of return to upper extremity activity. Secondary outcome measures included return to duty, complications, and revision surgery. RESULTS: Nineteen patients were included with average age 31 years and median 37 months' follow-up. Ten were Mason III, 6 were part of a terrible triad injury, and the remainder were fracture-dislocations. At an average follow-up of 3.7 years, 15 patients returned to active military duty, and 9 resumed their regular upper extremity military function. At the time of final follow-up, the average DASH score was 13. Seven patients returned to their usual level of sport and exercise, 6 at a reduced level, and 6 did not resume physical exercises secondary to pain or stiffness. Sixteen adverse outcomes among 14 patients included symptomatic heterotopic ossification (5 of 19) and neurological sequelae (4 of 19). Three elected to have a revision procedure at an average of 13 months for heterotopic ossification or loosening. CONCLUSIONS: Among active patients with radial head fractures treated with RHA, three-quarters will return to active duty military service, push-ups, and sport; however, half may report an adverse outcome unrelated to the prosthesis and only about half of patients will return to their preinjury level of function. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

RESUMEN

Fractures of the fifth metacarpal neck, or boxer's fractures, are common, particularly among young men. Because of the high frequency of this injury, there is a considerable range of treatment options. The purpose of this systematic review was to determine whether reduction and splint or cast immobilization is necessary for fractures of the fifth metacarpal neck. The authors conducted a systematic review of all published studies that randomized these fractures to cast immobilization vs treatment with soft wrap without reduction. Cast immobilization is not superior to soft wrap without reduction in most cases. The study found that reduction and cast immobilization is not necessary for boxer's fractures.

RESUMEN

We present the novel use of particulated juvenile cartilage transfer in the upper extremity. Our patient is an active duty solider with an osteochondral defect (OCD) of the capitellum that he sustained after an improvised explosive devise injury to his left elbow.

RESUMEN

In the setting a near or complete upper extremity amputations with significant soft tissue loss and neurovascular compromise, upper extremity surgeons are faced with the challenge of limb salvage. There are a multitude of treatment options for managing skeletal and soft tissue injuries including provisional fixation, staged reconstruction, and an acute shortening osteotomy with primary rigid internal fixation. However, many complications are associated with these techniques. Complications of provisional fixation include pin tract infection and loosening, tethering of musculotendinous units, nonunion, and additional surgeries. Staged reconstruction includes a variety of techniques: distraction osteogenesis, bone transport, or vascularized and non-vascularized structural autograft or allograft, but the risks often outweigh the benefits. Risks include nonunion, postoperative vascular complications necessitating reoperation, and the inability to return to the previous level of function at an average of 24 months. Acute shortening osteotomy with internal fixation offers the advantage of a single-stage procedure that provides for decreasing the soft tissue loss, provides a rigid platform to protect the delicate neurovascular repair, and alleviates unwanted tension at the repair sites. This review discusses the literature on the surgical treatment of severe upper extremity trauma with associated neurovascular injury over the past 75 years, and aims to evaluate the indications, surgical techniques, clinical and functional outcomes, and complications associated with acute shortening osteotomy with rigid internal fixation. Although this technique is not without risks, it is well-tolerated in the acute setting with a complication profile comparable to other techniques of fixation while remaining a single procedure.
