Fractures of the lateral process of the talus have been associated with snowboarding, so much so that they have earned the nickname “snowboarder’s ankle”; these typically occur with relatively low-energy injuries when compared with fractures of the talar head, neck, and body. We have observed that snowboarding portends a higher risk of talus fractures when compared with skiing and can include higher energy injury patterns. This study describes a series of talar head, neck, and body fractures caused by snowboarding, their treatment, and outcomes. A retrospective chart review was performed on all surgical cases collected from 2007 to 2012 to include talar head, neck, body, or lateral process fractures sustained while snowboarding. Radiographs were reviewed and the fractures were characterized. Questionnaires, including the Foot and Ankle Disability Index (FADI), were mailed to the patients. The pre-operative reports, surgical treatments, and outcomes were evaluated. Nine patients were identified with fractures of the talus caused by a snowboarding injury. One patient sustained an isolated talar head fracture, three sustained isolated talar neck fractures, one patient had an isolated talar body fracture, and two patients had isolated lateral process fractures. Two patients had a combination of talar injuries. At 2.5 years mean follow-up (range 6 months to 5 years), none of the patients developed avascular necrosis, nonunion/malunion, or required subsequent surgery. FADI scores indicated good to excellent results post-operatively. Full article

The standard surgical approach for the fusion of the tarsometatarsal (TMT) joint involves a two-incision approach. Philpott et al. proposed a modified, single-incision dorsal approach that yields a similar exposure. This study compares the joint preparation between the standard and modified dorsal approach. Ten fresh frozen cadaver specimens were randomly assigned to receive either a standard or modified dorsal operative approach to the TMT joint. The joint surface was prepared, and the joint was disarticulated. Image analysis, using ImageJ, was performed by two blinded reviewers to assess the joint surface preparation and this was compared by surgical approach. There was no significant difference in the amount of joint prepared when comparing the standard versus modified dorsal approach for TMT joints one through three (p = 0.548, p = 0.310, p = 0.548). First, TMT was 67.6% prepared by the standard approach vs 71.7% by the modified dorsal approach, second TMT was 67.9% vs. 65.7%, and third TMT was 65.9% vs. 59.6%. With our findings, we demonstrate that a modified dorsal approach with a single incision did not limit the ability to prepare the joint space. This study adds credibility backed by data to those set forth by Philipott et al. Full article

Resilience is a dynamic construct defined as the ability to recover from stress. There is no literature examining the impact of resilience on outcomes following foot and ankle surgery. Retrospective analysis of patients who underwent first MTP arthrodesis from September 2011 to May 2020 were reviewed for patient characteristics and union status. PROMIS Physical Function (PF), Pain Interference (PI), Depression (D), and Foot Function Index (FFI) were collected. Resilience was measured using the Brief Resilience Scale. A multivariable linear regression analysis examining the impact of resilience on patient reported was conducted. At an average of 3.4 years postoperatively, resilience was found to independently affect patient reported outcomes across all instruments, except the FFI pain subscale. In the first study examining the impact of resilience following foot and ankle surgery, we found that resilience has an independent positive effect on overall physical function, disability, pain, and mental health following MTP arthrodesis. Preoperative resilience scores could be used to predict postoperative functional outcomes following MTP arthrodesis and guide postoperative rehabilitation. These findings help establish the role of early positive psychosocial characteristics within orthopaedic foot and ankle population. Full article

Background: metatarsal fractures are a commonly encountered musculoskeletal injury. Scant literature exists to support current treatment guidelines and few studies describe the functional or occupational outcomes of patients with lesser metatarsal fractures. The purpose of this study is to describe occupational outcomes for traumatic lesser metatarsal fractures in relation to current treatment guidelines. Methods: a retrospective review of metatarsal fractures in adult military patients 18 years and older was performed. Data included: patient demographics, fracture angulation and displacement, treatment modality, associated injuries, rate of return to active duty, requirement for additional surgeries, ability to run a 2-mile physical fitness test, and presence of permanent activity limitations. Treatment guideline criteria were applied and compared with the occupational outcomes measured. Results: 38 fractures were included. The mean age was 27.2 ± 7.8 (19–48). Here, 28 fractures were initially treated non-operatively. Fractures selected for non-operative treatment had a mean displacement of 1.7 +/− 1.1 mm and a mean angulation of 3.3 +/− 3.5° at initial presentation. Fractures selected for operative treatment had a mean displacement of 4.5 +/− 2.4 mm and a mean angulation of 15.7 +/− 13.8° at initial presentation. The return to run rate was 89% in non-operatively treated patients and 50% in operatively treated patients (p = 0.02). Non-operative patients returned to running at a mean of 119 +/− 103 days and operative patients returned to running at a mean of 306 +/− 191 days (p = 0.0039). 50% of operatively treated patients and 11% of non-operatively treated patents were unable to remain in the military due to their metatarsal fractures. Conclusions: patients treated non-operatively were more likely to return to running and returned to running sooner than operatively treated patients. Current treatment guidelines could not be supported or refuted based upon the study results. The occupational and functional outcomes demonstrated in this study may assist surgeons in counseling patients on their planned treatment and anticipated recovery following a lesser metatarsal fracture.

While Achilles tendon injuries are common amongst the general population, there are very few cases in which simultaneous bilateral injuries occur. Medial malleolar fractures at the time of Achilles tendon rupture have been cited in the literature and are commonly missed. The following case outlines the presentation, treatment, and outcome of a United States Army Soldier with simultaneous bilateral Achilles tendon ruptures in addition to a unilateral right medial malleolar fracture. This patient was able to completely return to duty within 1 year after being treated with ORIF of the medial malleolus, bilateral end-to-end repair of the AT, and accelerated rehabilitation beginning at 2 weeks on the left and 6 weeks on the right.

Rotator cuff (RC) disease, defined as any pathological state of the rotator cuff, is one of the most common shoulder conditions worldwide. It accounts for 70% of shoulder pain and dysfunction in adults and is the third most prevalent musculoskeletal disorder. Currently, the main issue with rotator cuff disease is that surgery represents the most common treatment performed. However, rotator cuff surgeries have a high failure rate positively correlated with the severity of the tear, and a high re-tear rate. This review will focus on the current research perspectives of rotator cuff repairs as well as new advances in the field. Current research is shifting its focus to target the healing and tendon repair process in an aim to decrease the failure rates. The bulk of research right now is within biologic methods based on growth factors, repair scaffolds, and stem cells that promote healing. Among this, researchers are continuously trying to improve surgical techniques. The complement of both methods should pave the way for much more effective, longer-lasting rotator cuff repairs.
