Background: Grip lock is a high bar injury in male gymnastics and occurs while the gymnast is rotating around the high bar. Its mechanism and treatment have been poorly documented. Study Design: Case reports. Results: One gymnast sustained an extensor tendon injury and ulnar styloid fracture and was treated nonoperatively. The second gymnast sustained open fracture of the radius and ulna with extensor tendon ruptures and was surgically treated. Both gymnasts healed and were able to return to collegiate gymnastics despite residual finger extensor lag. Conclusions: Grip lock is a physically and psychologically devastating injury on the men’s high bar that can cause forearm fractures and extensor tendon injuries at the wrist (Zone 8), which may result in residual extensor tendon lag. Injuries may be prevented with proper grip fit, appropriate maintenance of grips, and limited duration of use, as well as education of athletes, athletic trainers, and coaches

Abstract Background While some traumatic closed index extensor tendon ruptures at the musclotendinous junction have been previously reported, closed index extensor tendon pseudorupture due to intertendinous attenuation is exceedingly rare with only one case report of a gymnastics-related sports injury in the English literature. Herein, we report two non-sports injury related cases of traumatic index extensor tendon attenuation mimicking closed tendon rupture, including the pathological findings and intraoperative video of the attenuated extensor indicis proprius tendon. Case presentation A 28-year-old man and a 30-year-old man caught their hands in a high-speed drill and lathe, respectively, which caused a sudden forced flexion of their wrists. They could not actively extend the metacarpophalangeal joints of their index fingers. Intraoperatively, although the extensor indicis proprius and index extensor digitorum communes tendons were in continuity without ruptures, both tendons were attenuated and stretched. The attenuated index extensor tendons were reconstructed either with shortening by plication or step-cut when the tendon damage was less severe or, in severely attenuated tendons, with tendon grafting (ipsilateral palmaris longus) or tendon transfer. Six months after the operation, the active extension of the index metacarpophalangeal joints had recovered well. Conclusions Two cases of traumatic index extensor tendon attenuation were treated successfully by shortening the attenuated tendon in combination with tendon graft or transfer. We recommend WALANT (wide-awake local anesthesia and no tourniquet) in the reconstruction surgery of index extensor tendon attenuation to determine the appropriate amount of tendon shortening or optimal tension for tendon grafting or transfer. Intraoperative voluntary finger movement is essential, as it is otherwise difficult to judge the stretch length of intratendinous elongation and extent of traumatic intramuscular damage affecting tendon excursion.

Extensor Lag

To compare the functional results of early controlled mobilisation and static immobilisation following repair of extensor tendons, we conducted a comparative study between two centres. In one, a consecutive series of tenorrhaphy patients was treated post-operatively by the dynamic splinting technique. In the other, a consecutive group was treated by static splinting. All patients treated by dynamic splinting were graded excellent within six weeks following surgery; no tendon ruptures occurred and no secondary corrective tendon surgery was required. After static splinting, 40% were graded excellent, 31% good, 29% fair, and none poor; six fingers treated by static splintage subsequently required tenolysis. Following surgical repair of extensor tendons of the hand, patients treated by early controlled motion regain better flexion function in terms of grip strength and pulp-to-palm distance. Dynamic splinting is a more effective technique than static splinting in the prevention of extensor lag.

Extensor Tendon Injuries

Extensor tendon injuries are widely believed to be straightforward problems that are relatively simple to manage. However, these injuries can be complex and demand a thorough understanding of anatomy to achieve the best functional outcomes. When lacerations occur in the forearm as in Zones VIII and IX injury, the repair of the extensor tendon and muscle, and posterior interosseous nerve (PIN) is often challenging. A review of the literature shows little guidance and attention for these injuries. We present four patients with injuries to Zones VIII and IX as well as a review of surgical technique, postoperative rehabilitation, and pearls that may be of benefit to those managing these injuries.

Extensor Lag

We assessed the outcome of tendon grafting of multiple finger extensor tendon ruptures in 14 patients with rheumatoid arthritis. Extensor lags improved from a preoperative mean of 33° (range, 20°–65°) to a postoperative mean of 18° (range, 0–60°). However, loss of finger flexion was observed, with a mean postoperative fingertip to palm distance of 1.6 (range: 0–7.5) cm. Patient satisfaction correlated with the fingertip to palm distance, though not with the postoperative extensor lag. Because of the loss of finger flexion which was probably due to muscle contracture, we conclude that the results of tendon grafts in this situation are unsatisfactory.

Extensor Tendon Injuries

Osteosynthesis of metacarpal and phalangeal fractures with headless compression screws leads to a defect in the articular surface and possibly damage to the extensor tendons. This study aimed to quantify the articular surface defect and extensor tendon injuries after implant placement in cadaveric hands. Defect size was assessed with computed tomography. Extensor tendon injuries were assessed by direct visualization and measurement after dissection. In the middle phalanx, the defect size in relation to the joint surface was significantly smaller after anterograde screw placement when compared with retrograde placement. Also, a mini-open approach was found to cause significantly less tendon injury than a percutaneous approach, but there was no difference in tendon damage between retrograde and antegrade screw insertion into the middle phalanx.

Review of the notes of 46 extensor tendon repairs in 21 patients treated by post-operative dynamic traction without an M.P. flexion block, no tendon ruptures or extensor lag and only one digit without full flexion after a mean follow-up of seven weeks. Re-examination of 26 treated repairs in nine patients for this study demonstrated a mean T.A.M. of 259° at an average 14 months follow-up. No bow-stringing occurred because the extensor retinaculum was not excised, and no tenolyses were necessary.

Extensor tendon repairs, although common, can be difficult injuries to treat. Their treatment is tailored to the zone of the hand that is affected since varying biomechanical forces are applied to the tendon at each zone. Prompt treatment is necessary to prevent potential complications associated with these injuries. This is particularly true of Zone V extensor tendon injuries, as their mechanism is commonly a highly infectious human bite. We present the case of a human fight bite resulting in a Zone V extensor tendon injury. The delayed presentation of this case resulted in an untreated infection that caused an abscess with associated extensor tendon necrosis and rupture. Given the large gap length between the ends of the tendons, tendon repair was performed using a palmaris longus autograft. Even when these are done in a controlled setting, adhesions are common. The compromised wound bed caused irritation, erosion, and subsequent rupture of the extensor tendon of the hand. In an effort to avoid common complications such as adhesion, the repair was then wrapped with human umbilical membrane (AVIVE® Soft Tissue Membrane, AxoGen Inc., Alachua, FL) to separate adjacent tissue and reduce inflammation. Even without access to formal physical therapy, our patient had excellent functional outcomes at his final follow-up visit. The patient was able to make a loose composite fist, had no extensor lag at the MCP joints, and had extensor lag of 15 degrees at the PIP joints of digits 4-5.
