Myositis ossificans traumatica causing ankylosis of the elbow.
We report a 13-year-old boy who presented with a 14-month history of a fixed elbow with no movement and a palpable bony mass in the anterior aspect of the elbow. He had sustained significant trauma to the affected limb 1 month prior to onset of symptoms, which was managed by native massage and bandaging for 4 weeks. The clinicoradiological diagnosis was suggestive of myositis ossificans, and the myositic mass was completely excised. Histopathology revealed lamellar bone. The 2-year follow-up showed full function of the affected limb and no signs of recurrence. We report this case of clinical interest due to the unusually l...

Autosomal dominant type I osteopetrosis is related with iatrogenic fractures in arthroplasty.
Authors: van Hove RP, de Jong T, Nolte PA Abstract Autosomal dominant osteopetrosis (ADO) is a sclerotic bone disorder due to failure of osteoclasts. ADO poses difficulties during arthroplasty because of the increased chance for iatrogenic fractures due to sclerotic bone. ADO is divided into two types based on radiological findings, fracture risk, and osteoclast activity. These differences suggest less brittle bone in patients with ADO I compared to that of patients with ADO II, which suggests a smaller chance of preoperative fractures during cementless arthroplasty in ADO I compared with that in ADO II. A case of ...

CONCLUSIONS: Anterior interbody fusion with a coriticocancellous allograft can significantly increase neuroforaminal dimension even in the absence of formal posterior distraction or foraminotomy; anterior interbody fusion with a coriticocancellous allograft has little effect on supradjacent neuroforaminal dimensions.

Is the supraspinatus muscle atrophy truly irreversible after surgical repair of rotator cuff tears?
Authors: Chung SW, Kim SH, Tae SK, Yoon JP, Choi JA, Oh JH Abstract BACKGROUND: Atrophy of rotator cuff muscles has been considered an irreversible phenomenon. The purpose of this study is to evaluate whether atrophy is truly irreversible after rotator cuff repair. METHODS: We measured supraspinatus muscle atrophy of 191 patients with full-thickness rotator cuff tears on preoperative magnetic resonance imaging and postoperative multidetector computed tomography images, taken at least 1 year after operation. The occupation ratio was calculated using Photoshop CS3 software. We compared the change between pre- and...

Indirect reduction maneuver and minimally invasive approach for displaced proximal humerus fractures in elderly patients.
CONCLUSIONS: The indirect reduction maneuver and minimally invasive approach were safe and reliable options for the treatment of displaced proximal humerus fractures in the elderly patients. An inadequate reduction (i.e., less than 110° NSA) or lack of medial support (e.g., no cortical or screw support) were significant factors contributing to poor functional outcomes.

Pulse oximetry for the diagnosis and prediction for surgical exploration in the pulseless perfused hand as a result of supracondylar fractures of the distal humerus.
CONCLUSIONS: The presence of a waveform on a pulse oximeter is a sensitive and easily available modality in determining vascular perfusion as compared to other more complex investigations. The high sensitivity of this test will allow surgeons to objectively determine the requirement for surgical exploration of the brachial artery.

Subluxation of the extensor carpi ulnaris tendon associated with the extensor digitorum tendon subluxation of the long finger.
Authors: Kim BS, Yoon HG, Kim HT, Park KH, Kim CG, Song HS Abstract A twenty-year-old male visited our clinic with wrist and long finger metacarpophalangeal (MP) joint pain. Dynamic ultrasonography revealed sagittal band (SB) ulnar subluxation and extensor carpi ulnaris (ECU) volar subluxation. Magnetic resonance imaging showed longitudinal splitting and dislocation of the volar half slip of the ECU tendon. The redundant radial SB was augmented and ECU sheath was advanced to the periosteum using suture anchors. He was able to perform his previous activities at the last follow-up.

Current biomechanical concepts for rotator cuff repair.
Authors: Lee TQ Abstract For the past few decades, the repair of rotator cuff tears has evolved significantly with advances in arthroscopy techniques, suture anchors and instrumentation. From the biomechanical perspective, the focus in arthroscopic repair has been on increasing fixation strength and restoration of the footprint contact characteristics to provide early rehabilitation and improve healing. To accomplish these objectives, various repair strategies and construct configurations have been developed for rotator cuff repair with the understanding that many factors contribute to the structural integrity of t...

Fifteen-year results of precoated femoral stem in primary hybrid total hip arthroplasty.

Symptomatic os infranaviculare.
Authors: Kim JK, Roh KJ Abstract The author observed a new accessory bone of the foot in the distal portion of navicular, which articulated with the medial cuneiform and the intermediate cuneiform, and named it os infranaviculare. A degenerative change was observed between the accessory bone and the navicular; this caused midfoot pain to the patient during weight-bearing. Thus, the patient was treated by excision of the accessory bone. The symptom was relieved at one-year postoperative.

Subtrochanteric femoral fracture during trochanteric nailing for the treatment of femoral shaft fracture.
We report on three cases of subtrochanteric femoral fractures during trochanteric intramedullary nailing for the treatment of femoral shaft fractures. Trochanteric intramedullary nails, which have a proximal lateral bend, are specifically designed for trochanteric insertion. When combined with the modified insertion technique, trochanteric intramedullary nails reduce iatrogenic fracture comminution and varus malalignment. We herein describe technical aspects of trochanteric intramedullary nailing for femoral shaft fractures to improve its application and prevent implant-derived complications.

Controversy exists regarding the best surgical technique to utilize to obtain gap balance. Some favor the use of a measured resection technique in which bone landmarks, such as the transepicondylar, the anterior-posterior, or the posterior condylar axes are used to determine proper femoral component rotation and subsequent gap balance. Others favor a gap balancing technique in which the femoral component is positioned parallel to the resected proximal tibia with each collateral li...

They are primarily associated with implantation of posterior cruciate substituting designs. These entities are the result of peripatellar fibrosynovial hyperplasia at the junction of the superior pole of the patella and the distal quadriceps tendon which becomes entrapped within the superior aspect of the intercondylar box of the femoral component during knee flexion.
