Dysfunction of the suprascapular nerve (SSN) is closely related to rotator cuff pathology; nerve dysfunction can lead to cuff disease and vice versa. Owing to repetitive microtrauma during overhead sports or massive cuff tears with significant tendon retraction, the SSN may suffer compression or traction neuropathy at the suprascapular notch. The SSN release technique has already been described.

Purpose: To prevent iatrogenic damage to the superficial peroneal nerve during ankle arthroscopy, it needs to be identified. The purpose of the present study was to determine which clinical test identified the superficial peroneal nerve most frequently and which determinants negatively affected the identification.
Methods: A total of 198 ankles (99 volunteers) were examined for identification of the superficial peroneal nerve.
Aims: The aim of this study was to report a single surgeon series of consecutive patients with moderate hallux valgus managed with a percutaneous extra-articular reverse-L chevron (PERC) osteotomy.
Patients And Methods: A total of 38 patients underwent 45 procedures. There were 35 women and three men.

Background: Arthroscopic ankle lateral ligament repair techniques have recently been developed and biomechanically as well as clinically validated. Although there has been 1 anatomic study relating suture and anchor proximity to anatomic structures, none has evaluated the ArthroBroström procedure.
Purpose: To evaluate the proximity of anatomic structures for the ArthroBroström lateral ankle ligament stabilization technique and to define ideal landmarks and "safe zones" for this repair.
Endoscopy for the posterior region of the ankle through two portals is becoming more widespread for the treatment of a large number of conditions which used to be treated with open surgery years ago. The tendon of the flexor hallucis longus (FHL) travels along an osteofibrous tunnel between the posterolateral and posteromedial tubercles of the talus. Chronic inflammation of this tendon may lead to painful stenosing tenosynovitis.

Consequently this has induced a renewed interest in surgical lengthening techniques, including proximal gastrocnemius release, to resolve gastrocnemius contracture in patients with foot disorders. This article describes and discusses the general anatomy of the triceps surae and the surgical anatomy of the gastrocnemius.

Purpose: The aim of this study was to determine which intra-articular injuries are associated with chronic anterolateral pain and functional instability after an ankle sprain.
Methods: From 2008 to 2010, records of all patients who underwent ankle joint arthroscopy with anterolateral pain and functional instability after an ankle sprain were reviewed. A systematic arthroscopic examination of the intra-articular structures of the ankle joint was performed.
Unlabelled: Lesser toe deformities are one of the most common conditions faced by orthopedic surgeons. Knowledge of the anatomy of the lesser toes is important for ensuring correct diagnosis and treatment of deformities, which are caused by factors such as muscle imbalance between the extensor apparatus and flexor tendons. However, this apparatus has not received sufficient attention in the literature.

Such injuries can present in the absence of a fracture. Therefore, diagnosis of these injuries can be challenging, and often stress radiographs are helpful.

Purpose: The purpose of this study was to assess the incidence of iatrogenic articular cartilage injuries during ankle arthroscopy and to determine the factors that caused them. The hypothesis of this study was that the incidence of iatrogenic cartilage injuries produced during ankle arthroscopic procedures is high and directly related to the arthroscopic technique.
Methods: All consecutive records from ankle arthroscopies performed between 2008 and 2010 were reviewed.
Introduction: Posterior ankle impingement is a clinical syndrome characterized by posterior ankle pain that is mainly presented on plantar flexion. The aim of this study is to compare and evaluate the results of posterior ankle impingement treated by endoscopic hindfoot posterior portals.
Materials And Methods: Between 2004 and 2009, a total of 38 endoscopic hindfoot procedures were performed to treat posterior ankle impingement.

Purpose: To study the safety and efficiency of posterior arthroscopic ankle arthrodesis.
Methods: Ten fresh-frozen human lower leg specimens without evidence of previous surgery to the foot and ankle were selected. Arthroscopic debridement of the tibiotalar joint was performed in all specimens using a standardized protocol.
Background: The first metatarsocuneiform joint is involved in first ray biomechanics and related forefoot pathology. The purpose of this study was to evaluate the first metatarsocuneiform joint radiographic findings in relation to angular position of the radiographic beam, and to assess the joint mobility as it relates to the anatomic orientation of the facets on both radiographic imaging and gross anatomic dissection.
Methods: Thirty-nine cadaveric lower extremity limbs were stratified as normal, mild, moderate, or severe hallux valgus deformity.
The presence and disposition of supernumerary tendons in the fourth extensor compartment of the wrist have been described by several authors. The aim of this communication was to describe a finding in a study of an anatomical dissection of an adult cadaver that presents a rare disposition of extensor tendons in the fourth extensor compartment of both wrists. In the right wrist, we found an extensor pollicis et indicis communis with three slips: two toward the index finger and one toward the thumb.

Methods: Fifty-six hamstring muscle groups were dissected in prone position from 29 human cadaveric specimens with a median age of 71.5 (range 45-98).
Background: Recently, arthroscopic-assisted techniques have been described to treat lateral ankle instability with excellent results. However, complications including neuritis of the superficial peroneal or sural nerve, and pain or discomfort due to a prominent anchor or suture knot have been reported. The aim of this study was to describe a novel technique, the "all-inside arthroscopic lateral collateral ankle ligament repair," and its results for treating patients with ankle instability.

Injury to the superior peroneal retinaculum, sometimes in association with a shallow fibular groove, can lead to this condition. There are several surgical treatments for recurrent peroneal tendon subluxation, but no tendoscopy technique has been reported to date.

Recent attention to the association of cartilaginous degeneration and hallux valgus may provide new insight into treatment algorithms and patient expectations. The purpose of this cadaveric study was to evaluate the degree of chondral damage as it relates to increasing hallux valgus deformity.
