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. The purpose of this study was to evaluate the outcomes in a young, active population after sustaining PLD/PLFD injuries. 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. 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. 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. The level of evidence is therapeutic IV.

Level IV: Systematic Review.

Background: Thumb trapeziometacarpal (TM) joint arthrosis is a common cause of thumb pain, which adversely affects hand function. Early arthrosis is characterized by capsular laxity, painful pinch and grip, and physical findings of joint tenderness and laxity. Dorsoradial capsulodesis (DRC) is a surgical technique used to stabilize the TM joint and treat early-stage arthrosis. We aim to evaluate the clinical outcomes of DRC for treating trapeziometacarpal instability in early-stage disease. Methods: Between 2003 and 2019, 23 patients underwent DRC. Patients with stage I TM arthritis and more than 6-month postoperative follow-up were included. Pain and disability scores were calculated along with physical examination and radiographic evaluation at the final follow-up. Results: At mean postoperative follow-up of 43.5 months, 13 patients with a mean age of 39.1 years were examined. The mean Disabilities of the Arm, Shoulder, and Hand score was 5.7, and visual analog pain score was 0.5. Patients had no significant difference in strength or range of motion in the ipsilateral versus contralateral hand. Follow-up radiographs did not demonstrate arthritic changes. Conclusions: Dorsoradial capsulodesis is a technically simple and reasonable option for stabilizing the TM joint in patients with early-stage arthrosis. This intervention showed no midterm progression to advanced arthritis in this cohort.

WC patients undergoing carpal tunnel release (CTR) fare poorly as compared with non-WC patients in nearly every metric. Higher rates of postoperative pain with delayed return to work can be anticipated in a WC cohort. In addition, WC patients receive suboptimal preoperative workup, and it is possible that unnecessary surgery is being completed in these cases. These findings are important to consider when treating the WC patient with CTS.

Patients who undergo open reduction and internal fixation of distal clavicle fractures have a high rate of hardware removal and persistence of symptoms, particularly when attempting to return to high-demand activities. This study evaluated the outcomes of military servicemembers after surgical treatment of distal clavicle fractures. The authors performed a retrospective analysis of active duty servicemembers who underwent open reduction and internal fixation of Neer type II distal clavicle fractures between October 17, 2007, and July 20, 2012, with a minimum of 2-year clinical follow-up. The electronic health record was queried to extract demographic features and clinical outcomes, primarily persistence of pain, removal of hardware, and postoperative return to high-level activity. A total of 48 patients were identified, with mean follow-up of 3.8 years. A total of 44% of patients underwent subsequent hardware removal. All fractures achieved radiographic union, and 35% of patients had persistence of symptoms. Patients who were treated with hook plating had a 3.64-fold higher risk of persistence of pain compared with those treated with conventional plating techniques. A total of 35% of patients successfully returned to full military function and completed a postoperative military deployment. Coracoclavicular reconstruction did not improve outcomes. Persistence of symptoms and requirement for hardware removal were not associated with the rate of postoperative deployment. Achieving excellent functional outcomes with open reduction and internal fixation of distal clavicle fractures remains a challenge. Where possible, conventional plate fixation should be considered over hook plate fixation. However, subsequent hardware removal and continuing shoulder pain do not preclude a return to high-level activity. [Orthopedics. 2018; 41(1):e117-e126.].

Background: Literature evaluating outcomes following operative fixation of Lisfranc injuries has demonstrated high rates of chronic disability, particularly in those returning to prior levels of physical function. The purpose of this study is to evaluate the occupational outcomes and return to running after open reduction and internal fixation (ORIF) or arthrodesis for Lisfranc fracture-dislocations in a moderate- to high-demand military cohort. Methods: All active-duty servicemembers undergoing ORIF or primary arthrodesis (Current Procedural Terminology 28615 and 28730, respectively) for confirmed Lisfranc fracture-dislocations (International Classification of Diseases, Ninth Revision codes 838.03 or 838.13) with minimum 2-year follow-up were isolated from the Military Health System. Demographic and surgical variables were recorded. Return to military function, return to running, perioperative morbidity, and rates of reoperation for complication were the outcomes of interest. Univariate analysis followed by multivariate logistic regression determined the association between patient demographics, type of fracture fixation (ie, ORIF vs arthrodesis) and functional outcomes, including medical separation. Results: Among Lisfranc injuries, 64 patients underwent ORIF while 6 underwent primary arthrodeses with a mean age of 28.1 years. At mean follow-up of 3.5 years (range, 2.0-6.3 years), 20% of servicemembers underwent medical separation due to limitations related to their injuries. body mass index (BMI) ≥30 kg/m2 (OR 17.67; 95% CI, 3.69-84.53) and Army or Marines service branch (OR 3.86; 95% CI, 1.08-13.86) were significant independent predictors for medical separation. Among servicemembers undergoing ORIF or primary arthrodeses, 69% returned to occupationally required daily running during the follow-up period. Servicemembers with a BMI <30 kg/m2 were more likely to return to running (OR 13.14, 95% CI, 2.50-69.19). Radiographic evidence of posttraumatic Lisfranc osteoarthritis occurred in 10 (16%) servicemembers who underwent internal fixation, and 82% of ORIF patients underwent implant removal. Conclusions: At mean 3.5-year follow-up, 80% of servicemembers undergoing ORIF or primary arthrodeses for Lisfranc injuries remained on active duty or successfully completed their military service, and 69% were able to resume occupationally required daily running. Surgeons should preoperatively counsel patients with these injuries on the possibility of persistent long-term disability. Levels of Evidence: Level IV: Retrospective series
